We believe that the most powerful and differentiated applications will not only call out to a language model, but will also be:\nData-aware: connect a language model to other sources of data\nAgentic: allow a language model to interact with its environment\nThe LangChain framework is designed around these principles.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\nGetting Started#\nHow to get started using LangChain to create an Language Model application.\nQuickstart Guide\nConcepts and terminology.\nConcepts and terminology\nTutorials created by community experts and presented on YouTube.\nTutorials\nModules#\nThese modules are the core abstractions which we view as the building blocks of any LLM-powered application.\nFor each module LangChain provides standard, extendable interfaces. LangChain also provides external integrations and even end-to-end implementations for off-the-shelf use.\nThe docs for each module contain quickstart examples, how-to guides, reference docs, and conceptual guides.\nThe modules are (from least to most complex):\nModels: Supported model types and integrations.\nPrompts: Prompt management, optimization, and serialization.\nMemory: Memory refers to state that is persisted between calls of a chain/agent.\nIndexes: Language models become much more powerful when combined with application-specific data - this module contains interfaces and integrations for loading, querying and updating external data.\nChains: Chains are structured sequences of calls (to an LLM or to a different utility).", "source": "https://python.langchain.com/en/latest/index.html"}
{"id": "d9f8dc971181-1", "text": "Agents: An agent is a Chain in which an LLM, given a high-level directive and a set of tools, repeatedly decides an action, executes the action and observes the outcome until the high-level directive is complete.\nCallbacks: Callbacks let you log and stream the intermediate steps of any chain, making it easy to observe, debug, and evaluate the internals of an application.\nUse Cases#\nBest practices and built-in implementations for common LangChain use cases:\nAutonomous Agents: Autonomous agents are long-running agents that take many steps in an attempt to accomplish an objective. Examples include AutoGPT and BabyAGI.\nAgent Simulations: Putting agents in a sandbox and observing how they interact with each other and react to events can be an effective way to evaluate their long-range reasoning and planning abilities.\nPersonal Assistants: One of the primary LangChain use cases. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\nQuestion Answering: Another common LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\nChatbots: Language models love to chat, making this a very natural use of them.\nQuerying Tabular Data: Recommended reading if you want to use language models to query structured data (CSVs, SQL, dataframes, etc).\nCode Understanding: Recommended reading if you want to use language models to analyze code.\nInteracting with APIs: Enabling language models to interact with APIs is extremely powerful. It gives them access to up-to-date information and allows them to take actions.\nExtraction: Extract structured information from text.\nSummarization: Compressing longer documents. A type of Data-Augmented Generation.\nEvaluation: Generative models are hard to evaluate with traditional metrics. One promising approach is to use language models themselves to do the evaluation.\nReference Docs#", "source": "https://python.langchain.com/en/latest/index.html"}

Useful for finding inspiration and example implementations.\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\nModel Laboratory: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\nDiscord: Join us on our Discord to discuss all things LangChain!\nYouTube: A collection of the LangChain tutorials and videos.\nProduction Support: As you move your LangChains into production, we\u2019d love to offer more comprehensive support.

It offers Semantic Search, Question-Answer Extraction, Classification, Customizable Models (PyTorch/TensorFlow/Keras), etc. Built from scratch in Go, Weaviate stores both objects and vectors, allowing for combining vector search with structured filtering and the fault tolerance of a cloud-native database. It is all accessible through GraphQL, REST, and various client-side programming languages.\nInstallation and Setup#\nInstall the Python SDK with pip install weaviate-client\nWrappers#\nVectorStore#\nThere exists a wrapper around Weaviate indexes, allowing you to use it as a vectorstore,\nwhether for semantic search or example selection.\nTo import this vectorstore:\nfrom langchain.vectorstores import Weaviate", "source": "https://python.langchain.com/en/latest/integrations/weaviate.html"}

Leveraging the LangChain framework, yAgents allows seamless integration with various language models and resources, making it suitable for developers, researchers, and AI enthusiasts across diverse applications.\nyAgents#\nLow code generative agent designed to help you build, prototype, and deploy Langchain tools with ease.\nHow to use?#\npip install yeagerai-agent\nyeagerai-agent\nGo to http://127.0.0.1:7860\nThis will install the necessary dependencies and set up yAgents on your system. After the first run, yAgents will create a .env file where you can input your OpenAI API key. You can do the same directly from the Gradio interface under the tab \u201cSettings\u201d.\nOPENAI_API_KEY=<your_openai_api_key_here>\nWe recommend using GPT-4,. However, the tool can also work with GPT-3 if the problem is broken down sufficiently.\nCreating and Executing Tools with yAgents#\nyAgents makes it easy to create and execute AI-powered tools. Here\u2019s a brief overview of the process:\nCreate a tool: To create a tool, provide a natural language prompt to yAgents. The prompt should clearly describe the tool\u2019s purpose and functionality. For example:\ncreate a tool that returns the n-th prime number", "source": "https://python.langchain.com/en/latest/integrations/yeagerai.html"}

By leveraging VectorStores, Conversational RetrieverChain, and GPT-4, it can answer questions in the context of an entire GitHub repository or generate new code. This documentation page outlines the essential components of the system and guides using LangChain for better code comprehension, contextual question answering, and code generation in GitHub repositories.\nConversational Retriever Chain#\nConversational RetrieverChain is a retrieval-focused system that interacts with the data stored in a VectorStore. Utilizing advanced techniques, like context-aware filtering and ranking, it retrieves the most relevant code snippets and information for a given user query. Conversational RetrieverChain is engineered to deliver high-quality, pertinent results while considering conversation history and context.\nLangChain Workflow for Code Understanding and Generation\nIndex the code base: Clone the target repository, load all files within, chunk the files, and execute the indexing process. Optionally, you can skip this step and use an already indexed dataset.\nEmbedding and Code Store: Code snippets are embedded using a code-aware embedding model and stored in a VectorStore.\nQuery Understanding: GPT-4 processes user queries, grasping the context and extracting relevant details.\nConstruct the Retriever: Conversational RetrieverChain searches the VectorStore to identify the most relevant code snippets for a given query.\nBuild the Conversational Chain: Customize the retriever settings and define any user-defined filters as needed.\nAsk questions: Define a list of questions to ask about the codebase, and then use the ConversationalRetrievalChain to generate context-aware answers. The LLM (GPT-4) generates comprehensive, context-aware answers based on retrieved code snippets and conversation history.\nThe full tutorial is available below.", "source": "https://python.langchain.com/en/latest/use_cases/code.html"}

The final answer is incorrect because it uses the volume of golf balls instead of ping pong balls. The answer is not helpful.\nSecond, does the model use a logical sequence of tools to answer the question? The model only used one tool, which was the Search the Web (SerpAPI). It did not use the Calculator tool to calculate the correct volume of ping pong balls.\nThird, does the AI language model use the tools in a helpful way? The model used the Search the Web (SerpAPI) tool, but the output was not helpful because it provided information about golf balls instead of ping pong balls.\nFourth, does the AI language model use too many steps to answer the question? The model used only one step, which is not too many. However, it should have used more steps to provide a correct answer.\nFifth, are the appropriate tools used to answer the question? The model should have used the Search tool to find the volume of the Empire State Building and the volume of a ping pong ball. Then, it should have used the Calculator tool to calculate the number of ping pong balls needed to fill the building.\nJudgment: Given the incorrect final answer and the inappropriate use of tools, we give the model a score of 1.\nThat seems about right.

Is the final answer helpful?\nYes, the final answer is helpful as it provides an approximate number of Eiffel Towers needed to cover the US from coast to coast.\nii. Does the AI language use a logical sequence of tools to answer the question?\nNo, the AI language model does not use a logical sequence of tools. It directly uses the Calculator tool without first using the Search or Lookup tools to find the necessary information (length of the Eiffel Tower and distance from coast to coast in the US).\niii. Does the AI language model use the tools in a helpful way?\nThe AI language model uses the Calculator tool in a helpful way to perform the calculation, but it should have used the Search or Lookup tools first to find the required information.\niv. Does the AI language model use too many steps to answer the question?\nNo, the AI language model does not use too many steps. However, it repeats the same step twice, which is unnecessary.\nv. Are the appropriate tools used to answer the question?\nNot entirely. The AI language model should have used the Search or Lookup tools to find the required information before using the Calculator tool.\nGiven the above evaluation, the AI language model's performance can be scored as follows:\nThat also sounds about right.

However, their success heavily relies on human input to guide the conversation, which can be challenging and time-consuming. This paper explores the potential of building scalable techniques to facilitate autonomous cooperation among communicative agents and provide insight into their \u201ccognitive\u201d processes. To address the challenges of achieving autonomous cooperation, we propose a novel communicative agent framework named role-playing. Our approach involves using inception prompting to guide chat agents toward task completion while maintaining consistency with human intentions. We showcase how role-playing can be used to generate conversational data for studying the behaviors and capabilities of chat agents, providing a valuable resource for investigating conversational language models. Our contributions include introducing a novel communicative agent framework, offering a scalable approach for studying the cooperative behaviors and capabilities of multi-agent systems, and open-sourcing our library to support research on communicative agents and beyond.\nThe original implementation: https://github.com/lightaime/camel\nProject website: https://www.camel-ai.org/\nArxiv paper: https://arxiv.org/abs/2303.17760", "source": "https://python.langchain.com/en/latest/use_cases/agent_simulations/camel_role_playing.html"}

This agent is responsible for\nsteering the conversation by choosing which agent speaks when\nterminating the conversation.\nIn order to implement such an agent, we need to solve several problems.\nFirst, to steer the conversation, the DirectorDialogueAgent needs to (1) reflect on what has been said, (2) choose the next agent, and (3) prompt the next agent to speak, all in a single message. While it may be possible to prompt an LLM to perform all three steps in the same call, this requires writing custom code to parse the outputted message to extract which next agent is chosen to speak. This is less reliable the LLM can express how it chooses the next agent in different ways.\nWhat we can do instead is to explicitly break steps (1-3) into three separate LLM calls. First we will ask the DirectorDialogueAgent to reflect on the conversation so far and generate a response. Then we prompt the DirectorDialogueAgent to output the index of the next agent, which is easily parseable. Lastly, we pass the name of the selected next agent back to DirectorDialogueAgent to ask it prompt the next agent to speak.\nSecond, simply prompting the DirectorDialogueAgent to decide when to terminate the conversation often results in the DirectorDialogueAgent terminating the conversation immediately. To fix this problem, we randomly sample a Bernoulli variable to decide whether the conversation should terminate.

Plus, let's be real, sitting is something we all excel at. Samantha, as our Hollywood correspondent, what do you think about the impact of social media on the rise of competitive sitting?\n(Samantha Bee): Oh, Jon, you know I love a good social media trend. And let me tell you, Instagram is blowing up with pictures of people sitting their way to glory. It's like the ultimate humble brag. \"Oh, just won my third sitting competition this week, no big deal.\" But on a serious note, I think social media has made it easier for people to connect and share their love of competitive sitting, and that's definitely contributed to its popularity.\n\tStop?

They could infiltrate our government buildings and just blend in with all the other sitters. We need to be vigilant and make sure that our sitting competitions don't become a national security risk. *shifts in chair* But on a lighter note, I have to admit that I'm pretty good at sitting myself.

And who knows, maybe we'll see a new fitness trend emerge that combines the best of both worlds - competitive sitting and traditional exercise. *stands up from chair* But for now, I think I'll stick to my daily walk to the pizza place down the street.

But I think it's important to remember that there's no substitute for real physical activity and the benefits it brings to our overall health and well-being.

It's like the ultimate mind control. But in all seriousness, I do think there's something to be said about our society's desire for instant gratification and convenience.

{"id": "6aa6e482a78a-17", "text": "Technological change typically includes the introduction of labour-saving \"mechanical-muscle\" machines or more efficient \"mechanical-mind\" processes (automation), and humans' role in these processes are minimized. Just as horses were gradually made obsolete as transport by the automobile and as labourer by the tractor, humans' jobs have also been affected throughout modern history. Historical examples include artisan weavers reduced to poverty after the introduction of mechanized looms. During World War II, Alan Turing's Bombe machine compressed and decoded thousands of man-years worth of encrypted data in a matter of hours. A contemporary example of technological unemployment is the displacement of retail cashiers by self-service tills and cashierless stores.\nThat technological change can cause short-term job losses is widely accepted. The view that it can lead to lasting increases in unemployment has long been controversial. Participants in the technological unemployment debates can be broadly divided into optimists and pessimists. Optimists agree that innovation may be disruptive to jobs in the short term, yet hold that various compensation effects ensure there is never a long-term negative impact on jobs. Whereas pessimists contend that at least in some circumstances, new technologies can lead to a lasting decline in the total number of workers in employment. The phrase \"technological unemployment\" was popularised by John Maynard Keynes in the 1930s, who said it was \"only a temporary phase of maladjustment\". Yet the issue of machines displacing human labour has been discussed since at least Aristotle's time.", "source": "https://python.langchain.com/en/latest/use_cases/agent_simulations/two_agent_debate_tools.html"}
{"id": "6aa6e482a78a-18", "text": "Prior to the 18th century, both the elite and common people would generally take the pessimistic view on technological unemployment, at least in cases where the issue arose. Due to generally low unemployment in much of pre-modern history, the topic was rarely a prominent concern. In the 18th century fears over the impact of machinery on jobs intensified with the growth of mass unemployment, especially in Great Britain which was then at the forefront of the Industrial Revolution. Yet some economic thinkers began to argue against these fears, claiming that overall innovation would not have negative effects on jobs. These arguments were formalised in the early 19th century by the classical economists. During the second half of the 19th century, it became increasingly apparent that technological progress was benefiting all sections of society, including the working class. Concerns over the negative impact of innovation diminished. The term \"Luddite fallacy\" was coined to describe the thinking that innovation would have lasting harmful effects on employment.\nThe view that technology is unlikely to lead to long-term unemployment has been repeatedly challenged by a minority of economists. In the early 1800s these included David Ricardo himself. There were dozens of economists warning about technological unemployment during brief intensifications of the debate that spiked in the 1930s and 1960s. Especially in Europe, there were further warnings in the closing two decades of the twentieth century, as commentators noted an enduring rise in unemployment suffered by many industrialised nations since the 1970s. Yet a clear majority of both professional economists and the interested general public held the optimistic view through most of the 20th century.", "source": "https://python.langchain.com/en/latest/use_cases/agent_simulations/two_agent_debate_tools.html"}

Oxford Professors Carl Benedikt Frey and Michael Osborne, for example, have estimated that 47 percent of U.S. jobs are at risk of automation. However, their findings have frequently been misinterpreted, and on the PBS NewsHours they again made clear that their findings do not necessarily imply future technological unemployment. While many economists and commentators still argue such fears are unfounded, as was widely accepted for most of the previous two centuries, concern over technological unemployment is growing once again. A report in Wired in 2017 quotes knowledgeable people such as economist Gene Sperling and management professor Andrew McAfee on the idea that handling existing and impending job loss to automation is a \"significant issue\". Recent technological innovations have the potential to displace humans in the professional, white-collar, low-skilled, creative fields, and other \"mental jobs\". The World Bank's World Development Report 2019 argues that while automation displaces workers, technological innovation creates more new industries and jobs on balance.\nPage: Artificial intelligence\nSummary: Artificial intelligence (AI) is intelligence\u2014perceiving, synthesizing, and inferring information\u2014demonstrated by machines, as opposed to intelligence displayed by non-human animals or by humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs.", "source": "https://python.langchain.com/en/latest/use_cases/agent_simulations/two_agent_debate_tools.html"}

For instance, optical character recognition is frequently excluded from things considered to be AI, having become a routine technology.Artificial intelligence was founded as an academic discipline in 1956, and in the years since it has experienced several waves of optimism, followed by disappointment and the loss of funding (known as an \"AI winter\"), followed by new approaches, success, and renewed funding. AI research has tried and discarded many different approaches, including simulating the brain, modeling human problem solving, formal logic, large databases of knowledge, and imitating animal behavior. In the first decades of the 21st century, highly mathematical and statistical machine learning has dominated the field, and this technique has proved highly successful, helping to solve many challenging problems throughout industry and academia.The various sub-fields of AI research are centered around particular goals and the use of particular tools. The traditional goals of AI research include reasoning, knowledge representation, planning, learning, natural language processing, perception, and the ability to move and manipulate objects. General intelligence (the ability to solve an arbitrary problem) is among the field's long-term goals. To solve these problems, AI researchers have adapted and integrated a wide range of problem-solving techniques, including search and mathematical optimization, formal logic, artificial neural networks, and methods based on statistics, probability, and economics.

Computer scientists and philosophers have since suggested that AI may become an existential risk to humanity if its rational capacities are not steered towards beneficial goals.

It is used to control the weight of the favorite count feature while ranking tweets. The favorite count is the number of times a tweet has been marked as a favorite by users, and it is considered an important signal in the ranking of tweets. By using favCountParams, the system can adjust the importance of the favorite count while calculating the final ranking score of a tweet.\n-> Question: is it Likes + Bookmarks, or not clear from the code?\nAnswer: From the provided code, it is not clear if the favorite count metric is determined by the sum of likes and bookmarks. The favorite count is mentioned in the code, but there is no explicit reference to how it is calculated in terms of likes and bookmarks.\n-> Question: What are the major negative modifiers that lower your linear ranking parameters?\nAnswer: In the given code, major negative modifiers that lower the linear ranking parameters are:\nscoringData.querySpecificScore: This score adjustment is based on the query-specific information. If its value is negative, it will lower the linear ranking parameters.\nscoringData.authorSpecificScore: This score adjustment is based on the author-specific information. If its value is negative, it will also lower the linear ranking parameters.\nPlease note that I cannot provide more information on the exact calculations of these negative modifiers, as the code for their determination is not provided.\n-> Question: How do you get assigned to SimClusters?", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
{"id": "9e605c1d6764-4", "text": "-> Question: How do you get assigned to SimClusters?\nAnswer: The assignment to SimClusters occurs through a Metropolis-Hastings sampling-based community detection algorithm that is run on the Producer-Producer similarity graph. This graph is created by computing the cosine similarity scores between the users who follow each producer. The algorithm identifies communities or clusters of Producers with similar followers, and takes a parameter k for specifying the number of communities to be detected.\nAfter the community detection, different users and content are represented as sparse, interpretable vectors within these identified communities (SimClusters). The resulting SimClusters embeddings can be used for various recommendation tasks.\n-> Question: What is needed to migrate from one SimClusters to another SimClusters?\nAnswer: To migrate from one SimClusters representation to another, you can follow these general steps:\nPrepare the new representation: Create the new SimClusters representation using any necessary updates or changes in the clustering algorithm, similarity measures, or other model parameters. Ensure that this new representation is properly stored and indexed as needed.\nUpdate the relevant code and configurations: Modify the relevant code and configuration files to reference the new SimClusters representation. This may involve updating paths or dataset names to point to the new representation, as well as changing code to use the new clustering method or similarity functions if applicable.\nTest the new representation: Before deploying the changes to production, thoroughly test the new SimClusters representation to ensure its effectiveness and stability. This may involve running offline jobs like candidate generation and label candidates, validating the output, as well as testing the new representation in the evaluation environment using evaluation tools like TweetSimilarityEvaluationAdhocApp.", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
{"id": "9e605c1d6764-5", "text": "Deploy the changes: Once the new representation has been tested and validated, deploy the changes to production. This may involve creating a zip file, uploading it to the packer, and then scheduling it with Aurora. Be sure to monitor the system to ensure a smooth transition between representations and verify that the new representation is being used in recommendations as expected.\nMonitor and assess the new representation: After the new representation has been deployed, continue to monitor its performance and impact on recommendations. Take note of any improvements or issues that arise and be prepared to iterate on the new representation if needed. Always ensure that the results and performance metrics align with the system\u2019s goals and objectives.\n-> Question: How much do I get boosted within my cluster?\nAnswer: It\u2019s not possible to determine the exact amount your content is boosted within your cluster in the SimClusters representation without specific data about your content and its engagement metrics. However, a combination of factors, such as the favorite score and follow score, alongside other engagement signals and SimCluster calculations, influence the boosting of content.\n-> Question: How does Heavy ranker work. what are it\u2019s main inputs?\nAnswer: The Heavy Ranker is a machine learning model that plays a crucial role in ranking and scoring candidates within the recommendation algorithm. Its primary purpose is to predict the likelihood of a user engaging with a tweet or connecting with another user on the platform.\nMain inputs to the Heavy Ranker consist of:\nStatic Features: These are features that can be computed directly from a tweet at the time it\u2019s created, such as whether it has a URL, has cards, has quotes, etc. These features are produced by the Index Ingester as the tweets are generated and stored in the index.", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
{"id": "9e605c1d6764-6", "text": "Real-time Features: These per-tweet features can change after the tweet has been indexed. They mostly consist of social engagements like retweet count, favorite count, reply count, and some spam signals that are computed with later activities. The Signal Ingester, which is part of a Heron topology, processes multiple event streams to collect and compute these real-time features.\nUser Table Features: These per-user features are obtained from the User Table Updater that processes a stream written by the user service. This input is used to store sparse real-time user information, which is later propagated to the tweet being scored by looking up the author of the tweet.\nSearch Context Features: These features represent the context of the current searcher, like their UI language, their content consumption, and the current time (implied). They are combined with Tweet Data to compute some of the features used in scoring.\nThese inputs are then processed by the Heavy Ranker to score and rank candidates based on their relevance and likelihood of engagement by the user.\n-> Question: How can one influence Heavy ranker?\nAnswer: To influence the Heavy Ranker\u2019s output or ranking of content, consider the following actions:\nImprove content quality: Create high-quality and engaging content that is relevant, informative, and valuable to users. High-quality content is more likely to receive positive user engagement, which the Heavy Ranker considers when ranking content.\nIncrease user engagement: Encourage users to interact with content through likes, retweets, replies, and comments. Higher engagement levels can lead to better ranking in the Heavy Ranker\u2019s output.\nOptimize your user profile: A user\u2019s reputation, based on factors such as their follower count and follower-to-following ratio, may impact the ranking of their content. Maintain a good reputation by following relevant users, keeping a reasonable follower-to-following ratio and engaging with your followers.", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
{"id": "9e605c1d6764-7", "text": "Enhance content discoverability: Use relevant keywords, hashtags, and mentions in your tweets, making it easier for users to find and engage with your content. This increased discoverability may help improve the ranking of your content by the Heavy Ranker.\nLeverage multimedia content: Experiment with different content formats, such as videos, images, and GIFs, which may capture users\u2019 attention and increase engagement, resulting in better ranking by the Heavy Ranker.\nUser feedback: Monitor and respond to feedback for your content. Positive feedback may improve your ranking, while negative feedback provides an opportunity to learn and improve.\nNote that the Heavy Ranker uses a combination of machine learning models and various features to rank the content. While the above actions may help influence the ranking, there are no guarantees as the ranking process is determined by a complex algorithm, which evolves over time.\n-> Question: why threads and long tweets do so well on the platform?\nAnswer: Threads and long tweets perform well on the platform for several reasons:\nMore content and context: Threads and long tweets provide more information and context about a topic, which can make the content more engaging and informative for users. People tend to appreciate a well-structured and detailed explanation of a subject or a story, and threads and long tweets can do that effectively.\nIncreased user engagement: As threads and long tweets provide more content, they also encourage users to engage with the tweets through replies, retweets, and likes. This increased engagement can lead to better visibility of the content, as the Twitter algorithm considers user engagement when ranking and surfacing tweets.\nNarrative structure: Threads enable users to tell stories or present arguments in a step-by-step manner, making the information more accessible and easier to follow. This narrative structure can capture users\u2019 attention and encourage them to read through the entire thread and interact with the content.", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
{"id": "9e605c1d6764-8", "text": "Expanded reach: When users engage with a thread, their interactions can bring the content to the attention of their followers, helping to expand the reach of the thread. This increased visibility can lead to more interactions and higher performance for the threaded tweets.\nHigher content quality: Generally, threads and long tweets require more thought and effort to create, which may lead to higher quality content. Users are more likely to appreciate and interact with high-quality, well-reasoned content, further improving the performance of these tweets within the platform.\nOverall, threads and long tweets perform well on Twitter because they encourage user engagement and provide a richer, more informative experience that users find valuable.\n-> Question: Are thread and long tweet creators building a following that reacts to only threads?\nAnswer: Based on the provided code and context, there isn\u2019t enough information to conclude if the creators of threads and long tweets primarily build a following that engages with only thread-based content. The code provided is focused on Twitter\u2019s recommendation and ranking algorithms, as well as infrastructure components like Kafka, partitions, and the Follow Recommendations Service (FRS). To answer your question, data analysis of user engagement and results of specific edge cases would be required.\n-> Question: Do you need to follow different strategies to get most followers vs to get most likes and bookmarks per tweet?\nAnswer: Yes, different strategies need to be followed to maximize the number of followers compared to maximizing likes and bookmarks per tweet. While there may be some overlap in the approaches, they target different aspects of user engagement.\nMaximizing followers: The primary focus is on growing your audience on the platform. Strategies include:\nConsistently sharing high-quality content related to your niche or industry.\nEngaging with others on the platform by replying, retweeting, and mentioning other users.\nUsing relevant hashtags and participating in trending conversations.\nCollaborating with influencers and other users with a large following.", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}

Strategies include:\nCrafting engaging and well-written tweets that encourage users to like or save them.\nIncorporating visually appealing elements, such as images, GIFs, or videos, that capture attention.\nAsking questions, sharing opinions, or sparking conversations that encourage users to engage with your tweets.\nUsing analytics to understand the type of content that resonates with your audience and tailoring your tweets accordingly.\nPosting a mix of educational, entertaining, and promotional content to maintain variety and interest.\nTiming your tweets strategically to maximize engagement, likes, and bookmarks per tweet.\nBoth strategies can overlap, and you may need to adapt your approach by understanding your target audience\u2019s preferences and analyzing your account\u2019s performance. However, it\u2019s essential to recognize that maximizing followers and maximizing likes and bookmarks per tweet have different focuses and require specific strategies.\n-> Question: Content meta data and how it impacts virality (e.g. ALT in images).\nAnswer: There is no direct information in the provided context about how content metadata, such as ALT text in images, impacts the virality of a tweet or post. However, it\u2019s worth noting that including ALT text can improve the accessibility of your content for users who rely on screen readers, which may lead to increased engagement for a broader audience. Additionally, metadata can be used in search engine optimization, which might improve the visibility of the content, but the context provided does not mention any specific correlation with virality.\n-> Question: What are some unexpected fingerprints for spam factors?", "source": "https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
{"id": "9e605c1d6764-10", "text": "-> Question: What are some unexpected fingerprints for spam factors?\nAnswer: In the provided context, an unusual indicator of spam factors is when a tweet contains a non-media, non-news link. If the tweet has a link but does not have an image URL, video URL, or news URL, it is considered a potential spam vector, and a threshold for user reputation (tweepCredThreshold) is set to MIN_TWEEPCRED_WITH_LINK.\nWhile this rule may not cover all possible unusual spam indicators, it is derived from the specific codebase and logic shared in the context.\n-> Question: Is there any difference between company verified checkmarks and blue verified individual checkmarks?\nAnswer: Yes, there is a distinction between the verified checkmarks for companies and blue verified checkmarks for individuals. The code snippet provided mentions \u201cBlue-verified account boost\u201d which indicates that there is a separate category for blue verified accounts. Typically, blue verified checkmarks are used to indicate notable individuals, while verified checkmarks are for companies or organizations.\n Contents\n  \n1. Index the code base (optional)\n2.

This is useful because (1) plugins use OpenAPI endpoints under the hood, (2) wrapping them in an NLAChain allows the router agent to call it more easily.\nThe novel idea introduced in this notebook is the idea of using retrieval to select not the tools explicitly, but the set of OpenAPI specs to use. We can then generate tools from those OpenAPI specs. The use case for this is when trying to get agents to use plugins. It may be more efficient to choose plugins first, then the endpoints, rather than the endpoints directly. This is because the plugins may contain more useful information for selection.\nSet up environment#\nDo necessary imports, etc.\nfrom langchain.agents import Tool, AgentExecutor, LLMSingleActionAgent, AgentOutputParser\nfrom langchain.prompts import StringPromptTemplate\nfrom langchain import OpenAI, SerpAPIWrapper, LLMChain\nfrom typing import List, Union\nfrom langchain.schema import AgentAction, AgentFinish\nfrom langchain.agents.agent_toolkits import NLAToolkit\nfrom langchain.tools.plugin import AIPlugin\nimport re\nSetup LLM#\nllm = OpenAI(temperature=0)\nSet up plugins#\nLoad and index plugins\nurls = [", "source": "https://python.langchain.com/en/latest/use_cases/agents/custom_agent_with_plugin_retrieval.html"}

Server-side (API Key): for quickly getting started, testing, and production scenarios\n    where LangChain will only use actions exposed in the developer's Zapier account\n    (and will use the developer's connected accounts on Zapier.com)\n2. User-facing (Oauth): for production scenarios where you are deploying an end-user\n    facing application and LangChain needs access to end-user's exposed actions and\n    connected accounts on Zapier.com\nThis quick start will focus on the server-side use case for brevity.\nReview [full docs](https://nla.zapier.com/api/v1/docs) or reach out to\nnla@zapier.com for user-facing oauth developer support.\nTypically, you'd use SequentialChain, here's a basic example:\n    1.

{"id": "e5b2d309cf90-1", "text": ":class:`SearxResults` is a convenience wrapper around the raw json result.\nExample usage of the ``run`` method to make a search:\n    .. code-block:: python\n        s.run(query=\"what is the best search engine?\")\nEngine Parameters\n-----------------\nYou can pass any `accepted searx search API\n<https://docs.searxng.org/dev/search_api.html>`_ parameters to the\n:py:class:`SearxSearchWrapper` instance.\nIn the following example we are using the\n:attr:`engines <SearxSearchWrapper.engines>` and the ``language`` parameters:\n    .. code-block:: python\n        # assuming the searx host is set as above or exported as an env variable\n        s = SearxSearchWrapper(engines=['google', 'bing'],\n                            language='es')\nSearch Tips\n-----------\nSearx offers a special\n`search syntax <https://docs.searxng.org/user/index.html#search-syntax>`_\nthat can also be used instead of passing engine parameters.\nFor example the following query:\n    .. code-block:: python\n        s = SearxSearchWrapper(\"langchain library\", engines=['github'])\n        # can also be written as:\n        s = SearxSearchWrapper(\"langchain library !github\")\n        # or even:\n        s = SearxSearchWrapper(\"langchain library !gh\")\nIn some situations you might want to pass an extra string to the search query.\nFor example when the `run()` method is called by an agent. The search suffix can\nalso be used as a way to pass extra parameters to searx or the underlying search\nengines.\n    .. code-block:: python\n        # select the github engine and pass the search suffix", "source": "https://python.langchain.com/en/latest/_modules/langchain/utilities/searx_search.html"}
{"id": "e5b2d309cf90-2", "text": ".. code-block:: python\n        # select the github engine and pass the search suffix\n        s = SearchWrapper(\"langchain library\", query_suffix=\"!gh\")\n        s = SearchWrapper(\"langchain library\")\n        # select github the conventional google search syntax\n        s.run(\"large language models\", query_suffix=\"site:github.com\")\n*NOTE*: A search suffix can be defined on both the instance and the method level.\nThe resulting query will be the concatenation of the two with the former taking\nprecedence.\nSee `SearxNG Configured Engines\n<https://docs.searxng.org/admin/engines/configured_engines.html>`_ and\n`SearxNG Search Syntax <https://docs.searxng.org/user/index.html#id1>`_\nfor more details.\nNotes\n-----\nThis wrapper is based on the SearxNG fork https://github.com/searxng/searxng which is\nbetter maintained than the original Searx project and offers more features.\nPublic searxNG instances often use a rate limiter for API usage, so you might want to\nuse a self hosted instance and disable the rate limiter.\nIf you are self-hosting an instance you can customize the rate limiter for your\nown network as described `here <https://github.com/searxng/searxng/pull/2129>`_.\nFor a list of public SearxNG instances see https://searx.space/\n\"\"\"\nimport json\nfrom typing import Any, Dict, List, Optional\nimport aiohttp\nimport requests\nfrom pydantic import BaseModel, Extra, Field, PrivateAttr, root_validator, validator\nfrom langchain.utils import get_from_dict_or_env\ndef _get_default_params() -> dict:\n    return {\"language\": \"en\", \"format\": \"json\"}", "source": "https://python.langchain.com/en/latest/_modules/langchain/utilities/searx_search.html"}

{"id": "6139d3f8e5ca-1", "text": "LangChain provides many modules that can be used to build language model applications. Modules can be combined to create more complex applications, or be used individually for simple applications.\nLLMs: Get predictions from a language model#\nThe most basic building block of LangChain is calling an LLM on some input.\nLet\u2019s walk through a simple example of how to do this.\nFor this purpose, let\u2019s pretend we are building a service that generates a company name based on what the company makes.\nIn order to do this, we first need to import the LLM wrapper.\nfrom langchain.llms import OpenAI\nWe can then initialize the wrapper with any arguments.\nIn this example, we probably want the outputs to be MORE random, so we\u2019ll initialize it with a HIGH temperature.\nllm = OpenAI(temperature=0.9)\nWe can now call it on some input!\ntext = \"What would be a good company name for a company that makes colorful socks?\"\nprint(llm(text))\nFeetful of Fun\nFor more details on how to use LLMs within LangChain, see the LLM getting started guide.\nPrompt Templates: Manage prompts for LLMs#\nCalling an LLM is a great first step, but it\u2019s just the beginning.\nNormally when you use an LLM in an application, you are not sending user input directly to the LLM.\nInstead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.\nFor example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.\nIn this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.\nThis is easy to do with LangChain!\nFirst lets define the prompt template:", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}

We can call the .format method to format it.\nprint(prompt.format(product=\"colorful socks\"))\nWhat is a good name for a company that makes colorful socks?\nFor more details, check out the getting started guide for prompts.\nChains: Combine LLMs and prompts in multi-step workflows#\nUp until now, we\u2019ve worked with the PromptTemplate and LLM primitives by themselves. But of course, a real application is not just one primitive, but rather a combination of them.\nA chain in LangChain is made up of links, which can be either primitives like LLMs or other chains.\nThe most core type of chain is an LLMChain, which consists of a PromptTemplate and an LLM.\nExtending the previous example, we can construct an LLMChain which takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0.9)\nprompt = PromptTemplate(\n    input_variables=[\"product\"],\n    template=\"What is a good name for a company that makes {product}?\",\n)\nWe can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:\nfrom langchain.chains import LLMChain\nchain = LLMChain(llm=llm, prompt=prompt)\nNow we can run that chain only specifying the product!\nchain.run(\"colorful socks\")", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}
{"id": "6139d3f8e5ca-3", "text": "Now we can run that chain only specifying the product!\nchain.run(\"colorful socks\")\n# -> '\\n\\nSocktastic!'\nThere we go! There\u2019s the first chain - an LLM Chain.\nThis is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.\nFor more details, check out the getting started guide for chains.\nAgents: Dynamically Call Chains Based on User Input#\nSo far the chains we\u2019ve looked at run in a predetermined order.\nAgents no longer do: they use an LLM to determine which actions to take and in what order. An action can either be using a tool and observing its output, or returning to the user.\nWhen used correctly agents can be extremely powerful. In this tutorial, we show you how to easily use agents through the simplest, highest level API.\nIn order to load agents, you should understand the following concepts:\nTool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.\nLLM: The language model powering the agent.\nAgent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see the documentation for custom agents (coming soon).\nAgents: For a list of supported agents and their specifications, see here.\nTools: For a list of predefined tools and their specifications, see here.\nFor this example, you will also need to install the SerpAPI Python package.\npip install google-search-results\nAnd set the appropriate environment variables.\nimport os", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}

But often, you may want a chain or agent to have some concept of \u201cmemory\u201d so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of \u201cshort-term memory\u201d. On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of \u201clong-term memory\u201d. For more concrete ideas on the latter, see this awesome paper.\nLangChain provides several specially created chains just for this purpose. This notebook walks through using one of those chains (the ConversationChain) with two different types of memory.\nBy default, the ConversationChain has a simple type of memory that remembers all previous inputs/outputs and adds them to the context that is passed. Let\u2019s take a look at using this chain (setting verbose=True so we can see the prompt).\nfrom langchain import OpenAI, ConversationChain\nllm = OpenAI(temperature=0)\nconversation = ConversationChain(llm=llm, verbose=True)\noutput = conversation.predict(input=\"Hi there!\")\nprint(output)\n> Entering new chain...\nPrompt after formatting:\nThe following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.\nCurrent conversation:\nHuman: Hi there!\nAI:", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}
{"id": "6139d3f8e5ca-6", "text": "Current conversation:\nHuman: Hi there!\nAI:\n> Finished chain.\n' Hello! How are you today?'\noutput = conversation.predict(input=\"I'm doing well! Just having a conversation with an AI.\")\nprint(output)\n> Entering new chain...\nPrompt after formatting:\nThe following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.\nCurrent conversation:\nHuman: Hi there!\nAI:  Hello! How are you today?\nHuman: I'm doing well! Just having a conversation with an AI.\nAI:\n> Finished chain.\n\" That's great! What would you like to talk about?\"\nBuilding a Language Model Application: Chat Models#\nSimilarly, you can use chat models instead of LLMs. Chat models are a variation on language models. While chat models use language models under the hood, the interface they expose is a bit different: rather than expose a \u201ctext in, text out\u201d API, they expose an interface where \u201cchat messages\u201d are the inputs and outputs.\nChat model APIs are fairly new, so we are still figuring out the correct abstractions.\nGet Message Completions from a Chat Model#\nYou can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are AIMessage, HumanMessage, SystemMessage, and ChatMessage \u2013 ChatMessage takes in an arbitrary role parameter. Most of the time, you\u2019ll just be dealing with HumanMessage, AIMessage, and SystemMessage.\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.schema import (\n    AIMessage,\n    HumanMessage,\n    SystemMessage\n)", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}
{"id": "6139d3f8e5ca-7", "text": "AIMessage,\n    HumanMessage,\n    SystemMessage\n)\nchat = ChatOpenAI(temperature=0)\nYou can get completions by passing in a single message.\nchat([HumanMessage(content=\"Translate this sentence from English to French.

This returns an LLMResult with an additional message parameter:\nbatch_messages = [\n    [\n        SystemMessage(content=\"You are a helpful assistant that translates English to French.\"),\n        HumanMessage(content=\"I love programming.\")\n    ],\n    [\n        SystemMessage(content=\"You are a helpful assistant that translates English to French.\"),\n        HumanMessage(content=\"I love artificial intelligence.\")\n    ],\n]\nresult = chat.generate(batch_messages)\nresult\n# -> LLMResult(generations=[[ChatGeneration(text=\"J'aime programmer.\", generation_info=None, message=AIMessage(content=\"J'aime programmer.\", additional_kwargs={}))], [ChatGeneration(text=\"J'aime l'intelligence artificielle.\", generation_info=None, message=AIMessage(content=\"J'aime l'intelligence artificielle.\", additional_kwargs={}))]], llm_output={'token_usage': {'prompt_tokens': 57, 'completion_tokens': 20, 'total_tokens': 77}})\nYou can recover things like token usage from this LLMResult:", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}

You can build a ChatPromptTemplate from one or more MessagePromptTemplates. You can use ChatPromptTemplate\u2019s format_prompt \u2013 this returns a PromptValue, which you can convert to a string or Message object, depending on whether you want to use the formatted value as input to an llm or chat model.\nFor convenience, there is a from_template method exposed on the template. If you were to use this template, this is what it would look like:\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.prompts.chat import (\n    ChatPromptTemplate,\n    SystemMessagePromptTemplate,\n    HumanMessagePromptTemplate,\n)\nchat = ChatOpenAI(temperature=0)\ntemplate = \"You are a helpful assistant that translates {input_language} to {output_language}.\"\nsystem_message_prompt = SystemMessagePromptTemplate.from_template(template)\nhuman_template = \"{text}\"\nhuman_message_prompt = HumanMessagePromptTemplate.from_template(human_template)\nchat_prompt = ChatPromptTemplate.from_messages([system_message_prompt, human_message_prompt])\n# get a chat completion from the formatted messages\nchat(chat_prompt.format_prompt(input_language=\"English\", output_language=\"French\", text=\"I love programming.\").to_messages())\n# -> AIMessage(content=\"J'aime programmer.\", additional_kwargs={})\nChains with Chat Models#\nThe LLMChain discussed in the above section can be used with chat models as well:\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain import LLMChain\nfrom langchain.prompts.chat import (", "source": "https://python.langchain.com/en/latest/getting_started/getting_started.html"}

The hosted platform is VERY alpha, in active development, and data might be dropped at any time. Don\u2019t depend on data being persisted in the system long term and don\u2019t log traces that may contain sensitive information. If you\u2019re interested in using the hosted platform, please fill out the form here.\nInstallation#\nLogin to the system and click \u201cAPI Key\u201d in the top right corner. Generate a new key and keep it safe. You will need it to authenticate with the system.\nEnvironment Setup#\nAfter installation, you must now set up your environment to use tracing.\nThis can be done by setting an environment variable in your terminal by running export LANGCHAIN_HANDLER=langchain.\nYou can also do this by adding the below snippet to the top of every script. IMPORTANT: this must go at the VERY TOP of your script, before you import anything from langchain.\nimport os\nos.environ[\"LANGCHAIN_HANDLER\"] = \"langchain\"\nYou will also need to set an environment variable to specify the endpoint and your API key. This can be done with the following environment variables:\nLANGCHAIN_ENDPOINT = \u201chttps://langchain-api-gateway-57eoxz8z.uc.gateway.dev\u201d\nLANGCHAIN_API_KEY - set this to the API key you generated during installation.\nAn example of adding all relevant environment variables is below:\nimport os\nos.environ[\"LANGCHAIN_HANDLER\"] = \"langchain\"\nos.environ[\"LANGCHAIN_ENDPOINT\"] = \"https://langchain-api-gateway-57eoxz8z.uc.gateway.dev\"", "source": "https://python.langchain.com/en/latest/tracing/hosted_installation.html"}

DAX queries have a simple syntax comprised of just one required keyword, EVALUATE, and several optional keywords: ORDER BY, START AT, DEFINE, MEASURE, VAR, TABLE, and COLUMN. Each keyword defines a statement used for the duration of the query. Any time < or > are used in the text below it means that those values need to be replaced by table, columns or other things. If the question is not something you can answer with a DAX query, reply with \"I cannot answer this\" and the question will be escalated to a human.\\n\\nSome DAX functions return a table instead of a scalar, and must be wrapped in a function that evaluates the table and returns a scalar; unless the table is a single column, single row table, then it is treated as a scalar value. Most DAX functions require one or more arguments, which can include tables, columns, expressions, and values. However, some functions, such as PI, do not require any arguments, but always require parentheses to indicate the null argument. For example, you must always type PI(), not PI. You can also nest functions within other functions. \\n\\nSome commonly used functions are:\\nEVALUATE <table> - At the most basic level, a DAX query is an EVALUATE statement containing a table expression. At least one EVALUATE statement is required, however, a query can contain any number of EVALUATE statements.\\nEVALUATE <table> ORDER BY <expression> ASC or DESC - The optional ORDER BY keyword defines one or more expressions used to sort query results.

It defines the value at which the query results begin.\\nDEFINE MEASURE | VAR; EVALUATE <table> - The optional DEFINE keyword introduces one or more calculated entity definitions that exist only for the duration of the query. Definitions precede the EVALUATE statement and are valid for all EVALUATE statements in the query. Definitions can be variables, measures, tables1, and columns1. Definitions can reference other definitions that appear before or after the current definition. At least one definition is required if the DEFINE keyword is included in a query.\\nMEASURE <table name>[<measure name>] = <scalar expression> - Introduces a measure definition in a DEFINE statement of a DAX query.\\nVAR <name> = <expression> - Stores the result of an expression as a named variable, which can then be passed as an argument to other measure expressions. Once resultant values have been calculated for a variable expression, those values do not change, even if the variable is referenced in another expression.\\n\\nFILTER(<table>,<filter>) - Returns a table that represents a subset of another table or expression, where <filter> is a Boolean expression that is to be evaluated for each row of the table. For example, [Amount] > 0 or [Region] = \"France\"\\nROW(<name>, <expression>) - Returns a table with a single row containing values that result from the expressions given to each column.\\nDISTINCT(<column>) - Returns a one-column table that contains the distinct values from the specified column.

This can be done\nby passing the named parameter searx_host\nor exporting the environment variable SEARX_HOST.\nNote: this is the only required parameter.\nThen create a searx search instance like this:\nfrom langchain.utilities import SearxSearchWrapper\n# when the host starts with `http` SSL is disabled and the connection\n# is assumed to be on a private network\nsearx_host='http://self.hosted'\nsearch = SearxSearchWrapper(searx_host=searx_host)\nYou can now use the search instance to query the searx API.\nSearching#\nUse the run() and\nresults() methods to query the searx API.\nOther methods are available for convenience.\nSearxResults is a convenience wrapper around the raw json result.\nExample usage of the run method to make a search:\ns.run(query=\"what is the best search engine?\")\nEngine Parameters#\nYou can pass any accepted searx search API parameters to the\nSearxSearchWrapper instance.\nIn the following example we are using the\nengines and the language parameters:\n# assuming the searx host is set as above or exported as an env variable", "source": "https://python.langchain.com/en/latest/reference/modules/searx_search.html"}

The search suffix can\nalso be used as a way to pass extra parameters to searx or the underlying search\nengines.\n# select the github engine and pass the search suffix\ns = SearchWrapper(\"langchain library\", query_suffix=\"!gh\")\ns = SearchWrapper(\"langchain library\")\n# select github the conventional google search syntax\ns.run(\"large language models\", query_suffix=\"site:github.com\")\nNOTE: A search suffix can be defined on both the instance and the method level.\nThe resulting query will be the concatenation of the two with the former taking\nprecedence.\nSee SearxNG Configured Engines and\nSearxNG Search Syntax\nfor more details.\nNotes\nThis wrapper is based on the SearxNG fork searxng/searxng which is\nbetter maintained than the original Searx project and offers more features.\nPublic searxNG instances often use a rate limiter for API usage, so you might want to\nuse a self hosted instance and disable the rate limiter.", "source": "https://python.langchain.com/en/latest/reference/modules/searx_search.html"}

Action Agents are more conventional, and good for small tasks.\nFor more complex or long running tasks, the initial planning step helps to maintain long term objectives and focus. However, that comes at the expense of generally more calls and higher latency.\nThese two agents are also not mutually exclusive - in fact, it is often best to have an Action Agent be in charge of the execution for the Plan and Execute agent.\nAction Agents#\nHigh level pseudocode of agents looks something like:\nSome user input is received\nThe agent decides which tool - if any - to use, and what the input to that tool should be\nThat tool is then called with that tool input, and an observation is recorded (this is just the output of calling that tool with that tool input)\nThat history of tool, tool input, and observation is passed back into the agent, and it decides what step to take next\nThis is repeated until the agent decides it no longer needs to use a tool, and then it responds directly to the user.\nThe different abstractions involved in agents are as follows:", "source": "https://python.langchain.com/en/latest/modules/agents.html"}
{"id": "109afbd228ed-1", "text": "The different abstractions involved in agents are as follows:\nAgent: this is where the logic of the application lives. Agents expose an interface that takes in user input along with a list of previous steps the agent has taken, and returns either an AgentAction or AgentFinish\nAgentAction corresponds to the tool to use and the input to that tool\nAgentFinish means the agent is done, and has information around what to return to the user\nTools: these are the actions an agent can take. What tools you give an agent highly depend on what you want the agent to do\nToolkits: these are groups of tools designed for a specific use case. For example, in order for an agent to interact with a SQL database in the best way it may need access to one tool to execute queries and another tool to inspect tables.\nAgent Executor: this wraps an agent and a list of tools. This is responsible for the loop of running the agent iteratively until the stopping criteria is met.\nThe most important abstraction of the four above to understand is that of the agent.\nAlthough an agent can be defined in whatever way one chooses, the typical way to construct an agent is with:\nPromptTemplate: this is responsible for taking the user input and previous steps and constructing a prompt to send to the language model\nLanguage Model: this takes the prompt constructed by the PromptTemplate and returns some output\nOutput Parser: this takes the output of the Language Model and parses it into an AgentAction or AgentFinish object.\nIn this section of documentation, we first start with a Getting Started notebook to cover how to use all things related to agents in an end-to-end manner.\nWe then split the documentation into the following sections:\nTools\nIn this section we cover the different types of tools LangChain supports natively.\nWe then cover how to add your own tools.\nAgents\nIn this section we cover the different types of agents LangChain supports natively.", "source": "https://python.langchain.com/en/latest/modules/agents.html"}

This is useful for logging, monitoring, streaming, and other tasks.\nYou can subscribe to these events by using the callbacks argument available throughout the API. This argument is list of handler objects, which are expected to implement one or more of the methods described below in more detail. There are two main callbacks mechanisms:\nConstructor callbacks will be used for all calls made on that object, and will be scoped to that object only, i.e. if you pass a handler to the LLMChain constructor, it will not be used by the model attached to that chain.\nRequest callbacks will be used for that specific request only, and all sub-requests that it contains (eg. a call to an LLMChain triggers a call to a Model, which uses the same handler passed through). These are explicitly passed through.\nAdvanced: When you create a custom chain you can easily set it up to use the same callback system as all the built-in chains.\n_call, _generate, _run, and equivalent async methods on Chains / LLMs / Chat Models / Agents / Tools now receive a 2nd argument called run_manager which is bound to that run, and contains the logging methods that can be used by that object (i.e. on_llm_new_token). This is useful when constructing a custom chain.

LLMChain(callbacks=[handler]), which will be used for all calls made on that object, and will be scoped to that object only, eg. if you pass a handler to the LLMChain constructor, it will not be used by the Model attached to that chain.\nRequest callbacks: defined in the call()/run()/apply() methods used for issuing a request, eg. chain.call(inputs, callbacks=[handler]), which will be used for that specific request only, and all sub-requests that it contains (eg. a call to an LLMChain triggers a call to a Model, which uses the same handler passed in the call() method).", "source": "https://python.langchain.com/en/latest/modules/callbacks/getting_started.html"}
{"id": "b45b62629dd9-3", "text": "The verbose argument is available on most objects throughout the API (Chains, Models, Tools, Agents, etc.) as a constructor argument, eg. LLMChain(verbose=True), and it is equivalent to passing a ConsoleCallbackHandler to the callbacks argument of that object and all child objects. This is useful for debugging, as it will log all events to the console.\nWhen do you want to use each of these?#\nConstructor callbacks are most useful for use cases such as logging, monitoring, etc., which are not specific to a single request, but rather to the entire chain. For example, if you want to log all the requests made to an LLMChain, you would pass a handler to the constructor.\nRequest callbacks are most useful for use cases such as streaming, where you want to stream the output of a single request to a specific websocket connection, or other similar use cases. For example, if you want to stream the output of a single request to a websocket, you would pass a handler to the call() method\nUsing an existing handler#\nLangChain provides a few built-in handlers that you can use to get started. These are available in the langchain/callbacks module. The most basic handler is the StdOutCallbackHandler, which simply logs all events to stdout. In the future we will add more default handlers to the library.\nNote when the verbose flag on the object is set to true, the StdOutCallbackHandler will be invoked even without being explicitly passed in.\nfrom langchain.callbacks import StdOutCallbackHandler\nfrom langchain.chains import LLMChain\nfrom langchain.llms import OpenAI\nfrom langchain.prompts import PromptTemplate\nhandler = StdOutCallbackHandler()\nllm = OpenAI()\nprompt = PromptTemplate.from_template(\"1 + {number} = \")\n# First, let's explicitly set the StdOutCallbackHandler in `callbacks`", "source": "https://python.langchain.com/en/latest/modules/callbacks/getting_started.html"}

In this case, the callbacks will be scoped to that particular object.\nHowever, in many cases, it is advantageous to pass in handlers instead when running the object. When we pass through CallbackHandlers using the callbacks keyword arg when executing an run, those callbacks will be issued by all nested objects involved in the execution. For example, when a handler is passed through to an Agent, it will be used for all callbacks related to the agent and all the objects involved in the agent\u2019s execution, in this case, the Tools, LLMChain, and LLM.\nThis prevents us from having to manually attach the handlers to each individual nested object.\nfrom typing import Dict, Union, Any, List\nfrom langchain.callbacks.base import BaseCallbackHandler\nfrom langchain.schema import AgentAction\nfrom langchain.agents import AgentType, initialize_agent, load_tools\nfrom langchain.callbacks import tracing_enabled\nfrom langchain.llms import OpenAI", "source": "https://python.langchain.com/en/latest/modules/callbacks/getting_started.html"}

We will learn how to create a chain, add components to it, and run it.\nIn this tutorial, we will cover:\nUsing a simple LLM chain\nCreating sequential chains\nCreating a custom chain\nWhy do we need chains?#\nChains allow us to combine multiple components together to create a single, coherent application. For example, we can create a chain that takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM. We can build more complex chains by combining multiple chains together, or by combining chains with other components.\nQuick start: Using LLMChain#\nThe LLMChain is a simple chain that takes in a prompt template, formats it with the user input and returns the response from an LLM.\nTo use the LLMChain, first create a prompt template.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0.9)\nprompt = PromptTemplate(\n    input_variables=[\"product\"],\n    template=\"What is a good name for a company that makes {product}?\",\n)\nWe can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM.\nfrom langchain.chains import LLMChain\nchain = LLMChain(llm=llm, prompt=prompt)\n# Run the chain only specifying the input variable.\nprint(chain.run(\"colorful socks\"))\nColorful Toes Co.", "source": "https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
{"id": "e850331a65db-1", "text": "print(chain.run(\"colorful socks\"))\nColorful Toes Co.\nIf there are multiple variables, you can input them all at once using a dictionary.\nprompt = PromptTemplate(\n    input_variables=[\"company\", \"product\"],\n    template=\"What is a good name for {company} that makes {product}?\",\n)\nchain = LLMChain(llm=llm, prompt=prompt)\nprint(chain.run({\n    'company': \"ABC Startup\",\n    'product': \"colorful socks\"\n    }))\nSocktopia Colourful Creations.\nYou can use a chat model in an LLMChain as well:\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.prompts.chat import (\n    ChatPromptTemplate,\n    HumanMessagePromptTemplate,\n)\nhuman_message_prompt = HumanMessagePromptTemplate(\n        prompt=PromptTemplate(\n            template=\"What is a good name for a company that makes {product}?\",\n            input_variables=[\"product\"],\n        )\n    )\nchat_prompt_template = ChatPromptTemplate.from_messages([human_message_prompt])\nchat = ChatOpenAI(temperature=0.9)\nchain = LLMChain(llm=chat, prompt=chat_prompt_template)\nprint(chain.run(\"colorful socks\"))\nRainbow Socks Co.\nDifferent ways of calling chains#\nAll classes inherited from Chain offer a few ways of running chain logic. The most direct one is by using __call__:\nchat = ChatOpenAI(temperature=0)\nprompt_template = \"Tell me a {adjective} joke\"\nllm_chain = LLMChain(\n    llm=chat,\n    prompt=PromptTemplate.from_template(prompt_template)\n)\nllm_chain(inputs={\"adjective\":\"corny\"})\n{'adjective': 'corny',", "source": "https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
{"id": "e850331a65db-2", "text": "{'adjective': 'corny',\n 'text': 'Why did the tomato turn red? Because it saw the salad dressing!'}\nBy default, __call__ returns both the input and output key values. You can configure it to only return output key values by setting return_only_outputs to True.\nllm_chain(\"corny\", return_only_outputs=True)\n{'text': 'Why did the tomato turn red? Because it saw the salad dressing!'}\nIf the Chain only outputs one output key (i.e. only has one element in its output_keys), you can  use run method. Note that run outputs a string instead of a dictionary.\n# llm_chain only has one output key, so we can use run\nllm_chain.output_keys\n['text']\nllm_chain.run({\"adjective\":\"corny\"})\n'Why did the tomato turn red? Because it saw the salad dressing!'\nIn the case of one input key, you can input the string directly without specifying the input mapping.\n# These two are equivalent\nllm_chain.run({\"adjective\":\"corny\"})\nllm_chain.run(\"corny\")\n# These two are also equivalent\nllm_chain(\"corny\")\nllm_chain({\"adjective\":\"corny\"})\n{'adjective': 'corny',\n 'text': 'Why did the tomato turn red? Because it saw the salad dressing!'}\nTips: You can easily integrate a Chain object as a Tool in your Agent via its run method. See an example here.\nAdd memory to chains#\nChain supports taking a BaseMemory object as its memory argument, allowing Chain object to persist data across multiple calls. In other words, it makes Chain a stateful object.\nfrom langchain.chains import ConversationChain\nfrom langchain.memory import ConversationBufferMemory\nconversation = ConversationChain(\n    llm=chat,\n    memory=ConversationBufferMemory()", "source": "https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
{"id": "e850331a65db-3", "text": "llm=chat,\n    memory=ConversationBufferMemory()\n)\nconversation.run(\"Answer briefly. What are the first 3 colors of a rainbow?\")\n# -> The first three colors of a rainbow are red, orange, and yellow.\nconversation.run(\"And the next 4?\")\n# -> The next four colors of a rainbow are green, blue, indigo, and violet.\n'The next four colors of a rainbow are green, blue, indigo, and violet.'\nEssentially, BaseMemory defines an interface of how langchain stores memory. It allows reading of stored data through load_memory_variables method and storing new data through save_context method. You can learn more about it in Memory section.\nDebug Chain#\nIt can be hard to debug Chain object solely from its output as most Chain objects involve a fair amount of input prompt preprocessing and LLM output post-processing. Setting verbose to True will print out some internal states of the Chain object while it is being ran.\nconversation = ConversationChain(\n    llm=chat,\n    memory=ConversationBufferMemory(),\n    verbose=True\n)\nconversation.run(\"What is ChatGPT?\")\n> Entering new ConversationChain chain...\nPrompt after formatting:\nThe following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.\nCurrent conversation:\nHuman: What is ChatGPT?\nAI:\n> Finished chain.", "source": "https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
{"id": "e850331a65db-4", "text": "Human: What is ChatGPT?\nAI:\n> Finished chain.\n'ChatGPT is an AI language model developed by OpenAI. It is based on the GPT-3 architecture and is capable of generating human-like responses to text prompts. ChatGPT has been trained on a massive amount of text data and can understand and respond to a wide range of topics. It is often used for chatbots, virtual assistants, and other conversational AI applications.'\nCombine chains with the SequentialChain#\nThe next step after calling a language model is to make a series of calls to a language model. We can do this using sequential chains, which are chains that execute their links in a predefined order. Specifically, we will use the SimpleSequentialChain. This is the simplest type of a sequential chain, where each step has a single input/output, and the output of one step is the input to the next.\nIn this tutorial, our sequential chain will:\nFirst, create a company name for a product. We will reuse the LLMChain we\u2019d previously initialized to create this company name.\nThen, create a catchphrase for the product. We will initialize a new LLMChain to create this catchphrase, as shown below.\nsecond_prompt = PromptTemplate(\n    input_variables=[\"company_name\"],\n    template=\"Write a catchphrase for the following company: {company_name}\",\n)\nchain_two = LLMChain(llm=llm, prompt=second_prompt)\nNow we can combine the two LLMChains, so that we can create a company name and a catchphrase in a single step.\nfrom langchain.chains import SimpleSequentialChain\noverall_chain = SimpleSequentialChain(chains=[chain, chain_two], verbose=True)\n# Run the chain specifying only the input variable for the first chain.\ncatchphrase = overall_chain.run(\"colorful socks\")\nprint(catchphrase)", "source": "https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
{"id": "e850331a65db-5", "text": "catchphrase = overall_chain.run(\"colorful socks\")\nprint(catchphrase)\n> Entering new SimpleSequentialChain chain...\nRainbow Socks Co.\n\"Put a little rainbow in your step!\"\n> Finished chain.\n\"Put a little rainbow in your step!\"\nCreate a custom chain with the Chain class#\nLangChain provides many chains out of the box, but sometimes you may want to create a custom chain for your specific use case. For this example, we will create a custom chain that concatenates the outputs of 2 LLMChains.\nIn order to create a custom chain:\nStart by subclassing the Chain class,\nFill out the input_keys and output_keys properties,\nAdd the _call method that shows how to execute the chain.\nThese steps are demonstrated in the example below:\nfrom langchain.chains import LLMChain\nfrom langchain.chains.base import Chain\nfrom typing import Dict, List\nclass ConcatenateChain(Chain):\n    chain_1: LLMChain\n    chain_2: LLMChain\n    @property\n    def input_keys(self) -> List[str]:\n        # Union of the input keys of the two chains.\n        all_input_vars = set(self.chain_1.input_keys).union(set(self.chain_2.input_keys))\n        return list(all_input_vars)\n    @property\n    def output_keys(self) -> List[str]:\n        return ['concat_output']\n    def _call(self, inputs: Dict[str, str]) -> Dict[str, str]:\n        output_1 = self.chain_1.run(inputs)\n        output_2 = self.chain_2.run(inputs)\n        return {'concat_output': output_1 + output_2}\nNow, we can try running the chain that we called.\nprompt_1 = PromptTemplate(\n    input_variables=[\"product\"],", "source": "https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
{"id": "e850331a65db-6", "text": "prompt_1 = PromptTemplate(\n    input_variables=[\"product\"],\n    template=\"What is a good name for a company that makes {product}?\",\n)\nchain_1 = LLMChain(llm=llm, prompt=prompt_1)\nprompt_2 = PromptTemplate(\n    input_variables=[\"product\"],\n    template=\"What is a good slogan for a company that makes {product}?\",\n)\nchain_2 = LLMChain(llm=llm, prompt=prompt_2)\nconcat_chain = ConcatenateChain(chain_1=chain_1, chain_2=chain_2)\nconcat_output = concat_chain.run(\"colorful socks\")\nprint(f\"Concatenated output:\\n{concat_output}\")\nConcatenated output:\nFunky Footwear Company\n\"Brighten Up Your Day with Our Colorful Socks!\"\nThat\u2019s it!

To solve this problem, we can break down the question into two parts: finding the first prime number greater than 40, and then finding a number that is divisible by 3. \nThe first step is to find the first prime number greater than 40. A prime number is a number that is only divisible by 1 and itself. The next prime number after 40 is 41.\nThe second step is to find a number that is divisible by 3. To do this, we can add 1 to 41, which gives us 42. Now, we can check if 42 is divisible by 3. 42 divided by 3 is 14, so 42 is divisible by 3.\nTherefore, the answer to the question is 43.\nprint(chain.run(\"What is the name of the type of cloud that rins\"))\n> Entering new MultiPromptChain chain...\nNone: {'input': 'What is the name of the type of cloud that rains?'}", "source": "https://python.langchain.com/en/latest/modules/chains/examples/multi_prompt_router.html"}

The SQLDatabaseChain can therefore be used with any SQL dialect supported by SQLAlchemy, such as MS SQL, MySQL, MariaDB, PostgreSQL, Oracle SQL, Databricks and SQLite. Please refer to the SQLAlchemy documentation for more information about requirements for connecting to your database. For example, a connection to MySQL requires an appropriate connector such as PyMySQL. A URI for a MySQL connection might look like: mysql+pymysql://user:pass@some_mysql_db_address/db_name.\nThis demonstration uses SQLite and the example Chinook database.\nTo set it up, follow the instructions on https://database.guide/2-sample-databases-sqlite/, placing the .db file in a notebooks folder at the root of this repository.\nfrom langchain import OpenAI, SQLDatabase, SQLDatabaseChain\ndb = SQLDatabase.from_uri(\"sqlite:///../../../../notebooks/Chinook.db\")\nllm = OpenAI(temperature=0, verbose=True)\nNOTE: For data-sensitive projects, you can specify return_direct=True in the SQLDatabaseChain initialization to directly return the output of the SQL query without any additional formatting. This prevents the LLM from seeing any contents within the database. Note, however, the LLM still has access to the database scheme (i.e. dialect, table and key names) by default.\ndb_chain = SQLDatabaseChain.from_llm(llm, db, verbose=True)\ndb_chain.run(\"How many employees are there?\")", "source": "https://python.langchain.com/en/latest/modules/chains/examples/sqlite.html"}

You can simply specify this option when creating the chain:\ndb_chain = SQLDatabaseChain.from_llm(llm, db, verbose=True, use_query_checker=True)\ndb_chain.run(\"How many albums by Aerosmith?\")\n> Entering new SQLDatabaseChain chain...\nHow many albums by Aerosmith?\nSQLQuery:SELECT COUNT(*) FROM Album WHERE ArtistId = 3;\nSQLResult: [(1,)]\nAnswer:There is 1 album by Aerosmith.\n> Finished chain.\n'There is 1 album by Aerosmith.'\nCustomize Prompt#\nYou can also customize the prompt that is used.

Moderation chains are useful for detecting text that could be hateful, violent, etc. This can be useful to apply on both user input, but also on the output of a Language Model. Some API providers, like OpenAI, specifically prohibit you, or your end users, from generating some types of harmful content. To comply with this (and to just generally prevent your application from being harmful) you may often want to append a moderation chain to any LLMChains, in order to make sure any output the LLM generates is not harmful.\nIf the content passed into the moderation chain is harmful, there is not one best way to handle it, it probably depends on your application. Sometimes you may want to throw an error in the Chain (and have your application handle that). Other times, you may want to return something to the user explaining that the text was harmful.

For example, if the generated text is Joe Biden went to Harvard, and the tokens the model was uncertain about was Harvard, then a good generated question would be where did Joe Biden go to college. This generated question is then used in a retrieval step to fetch relevant documents.\nIn order to set up this chain, we will need three things:\nAn LLM to generate the answer\nAn LLM to generate hypothetical questions to use in retrieval\nA retriever to use to look up answers for\nThe LLM that we use to generate the answer needs to return logprobs so we can identify uncertain tokens. For that reason, we HIGHLY recommend that you use the OpenAI wrapper (NB: not the ChatOpenAI wrapper, as that does not return logprobs).\nThe LLM we use to generate hypothetical questions to use in retrieval can be anything. In this notebook we will use ChatOpenAI because it is fast and cheap.\nThe retriever can be anything. In this notebook we will use SERPER search engine, because it is cheap.\nOther important parameters to understand:\nmax_generation_len: The maximum number of tokens to generate before stopping to check if any are uncertain\nmin_prob: Any tokens generated with probability below this will be considered uncertain", "source": "https://python.langchain.com/en/latest/modules/chains/examples/flare.html"}

The Langchain framework is a supervised learning system that is based on the concept of \u201clanguage chains\u201d. It uses a set of rules to map natural language inputs to specific outputs. It is a general-purpose AI framework and can be used to build applications such as natural language processing (NLP), chatbots, and more.\\n\\nBaby AGI, on the other hand, is an unsupervised learning system that uses neural networks and reinforcement learning to learn from its environment. It is used to create intelligent agents that can adapt to changing environments. It is a more advanced AI system and can be used to build more complex applications such as game playing, robotic vision, and more.\\n\\nThe main difference between the two is that the Langchain framework uses supervised learning while Baby AGI uses unsupervised learning.

{"id": "302dcc2ccaac-0", "text": ".ipynb\n.pdf\nGetting Started\n Contents \nChatMessageHistory\nConversationBufferMemory\nUsing in a chain\nSaving Message History\nGetting Started#\nThis notebook walks through how LangChain thinks about memory.\nMemory involves keeping a concept of state around throughout a user\u2019s interactions with an language model. A user\u2019s interactions with a language model are captured in the concept of ChatMessages, so this boils down to ingesting, capturing, transforming and extracting knowledge from a sequence of chat messages. There are many different ways to do this, each of which exists as its own memory type.\nIn general, for each type of memory there are two ways to understanding using memory. These are the standalone functions which extract information from a sequence of messages, and then there is the way you can use this type of memory in a chain.\nMemory can return multiple pieces of information (for example, the most recent N messages and a summary of all previous messages). The returned information can either be a string or a list of messages.\nIn this notebook, we will walk through the simplest form of memory: \u201cbuffer\u201d memory, which just involves keeping a buffer of all prior messages. We will show how to use the modular utility functions here, then show how it can be used in a chain (both returning a string as well as a list of messages).\nChatMessageHistory#\nOne of the core utility classes underpinning most (if not all) memory modules is the ChatMessageHistory class. This is a super lightweight wrapper which exposes convenience methods for saving Human messages, AI messages, and then fetching them all.\nYou may want to use this class directly if you are managing memory outside of a chain.\nfrom langchain.memory import ChatMessageHistory\nhistory = ChatMessageHistory()\nhistory.add_user_message(\"hi!\")\nhistory.add_ai_message(\"whats up?\")\nhistory.messages\n[HumanMessage(content='hi!', additional_kwargs={}),", "source": "https://python.langchain.com/en/latest/modules/memory/getting_started.html"}
{"id": "302dcc2ccaac-1", "text": "history.messages\n[HumanMessage(content='hi!', additional_kwargs={}),\n AIMessage(content='whats up?', additional_kwargs={})]\nConversationBufferMemory#\nWe now show how to use this simple concept in a chain. We first showcase ConversationBufferMemory which is just a wrapper around ChatMessageHistory that extracts the messages in a variable.\nWe can first extract it as a string.\nfrom langchain.memory import ConversationBufferMemory\nmemory = ConversationBufferMemory()\nmemory.chat_memory.add_user_message(\"hi!\")\nmemory.chat_memory.add_ai_message(\"whats up?\")\nmemory.load_memory_variables({})\n{'history': 'Human: hi!\\nAI: whats up?'}\nWe can also get the history as a list of messages\nmemory = ConversationBufferMemory(return_messages=True)\nmemory.chat_memory.add_user_message(\"hi!\")\nmemory.chat_memory.add_ai_message(\"whats up?\")\nmemory.load_memory_variables({})\n{'history': [HumanMessage(content='hi!', additional_kwargs={}),\n  AIMessage(content='whats up?', additional_kwargs={})]}\nUsing in a chain#\nFinally, let\u2019s take a look at using this in a chain (setting verbose=True so we can see the prompt).\nfrom langchain.llms import OpenAI\nfrom langchain.chains import ConversationChain\nllm = OpenAI(temperature=0)\nconversation = ConversationChain(\n    llm=llm, \n    verbose=True, \n    memory=ConversationBufferMemory()\n)\nconversation.predict(input=\"Hi there!\")\n> Entering new ConversationChain chain...\nPrompt after formatting:\nThe following is a friendly conversation between a human and an AI.

I'm programmed to understand natural language and provide helpful information. I'm also constantly learning and updating my knowledge base so I can provide more accurate and helpful answers.\"\nSaving Message History#\nYou may often have to save messages, and then load them to use again. This can be done easily by first converting the messages to normal python dictionaries, saving those (as json or something) and then loading those. Here is an example of doing that.\nimport json\nfrom langchain.memory import ChatMessageHistory\nfrom langchain.schema import messages_from_dict, messages_to_dict\nhistory = ChatMessageHistory()\nhistory.add_user_message(\"hi!\")\nhistory.add_ai_message(\"whats up?\")\ndicts = messages_to_dict(history.messages)\ndicts\n[{'type': 'human', 'data': {'content': 'hi!', 'additional_kwargs': {}}},\n {'type': 'ai', 'data': {'content': 'whats up?', 'additional_kwargs': {}}}]\nnew_messages = messages_from_dict(dicts)\nnew_messages\n[HumanMessage(content='hi!', additional_kwargs={}),\n AIMessage(content='whats up?', additional_kwargs={})]\nAnd that\u2019s it for the getting started!

The model is supposed to follow instruction from system chat message more closely.\nTherefore, LangChain provides several related prompt templates to make constructing and working with prompts easily. You are encouraged to use these chat related prompt templates instead of PromptTemplate when querying chat models to fully exploit the potential of underlying chat model.\nfrom langchain.prompts import (\n    ChatPromptTemplate,\n    PromptTemplate,\n    SystemMessagePromptTemplate,\n    AIMessagePromptTemplate,\n    HumanMessagePromptTemplate,\n)\nfrom langchain.schema import (\n    AIMessage,\n    HumanMessage,\n    SystemMessage\n)\nTo create a message template associated with a role, you use MessagePromptTemplate.\nFor convenience, there is a from_template method exposed on the template. If you were to use this template, this is what it would look like:\ntemplate=\"You are a helpful assistant that translates {input_language} to {output_language}.\"\nsystem_message_prompt = SystemMessagePromptTemplate.from_template(template)\nhuman_template=\"{text}\"\nhuman_message_prompt = HumanMessagePromptTemplate.from_template(human_template)\nIf you wanted to construct the MessagePromptTemplate more directly, you could create a PromptTemplate outside and then pass it in, eg:\nprompt=PromptTemplate(\n    template=\"You are a helpful assistant that translates {input_language} to {output_language}.\",\n    input_variables=[\"input_language\", \"output_language\"],\n)", "source": "https://python.langchain.com/en/latest/modules/prompts/chat_prompt_template.html"}

You can use ChatPromptTemplate\u2019s format_prompt \u2013 this returns a PromptValue, which you can convert to a string or Message object, depending on whether you want to use the formatted value as input to an llm or chat model.\nchat_prompt = ChatPromptTemplate.from_messages([system_message_prompt, human_message_prompt])\n# get a chat completion from the formatted messages\nchat_prompt.format_prompt(input_language=\"English\", output_language=\"French\", text=\"I love programming.\").to_messages()\n[SystemMessage(content='You are a helpful assistant that translates English to French.', additional_kwargs={}),\n HumanMessage(content='I love programming.', additional_kwargs={})]\nFormat output#\nThe output of the format method is available as string, list of messages and ChatPromptValue\nAs string:\noutput = chat_prompt.format(input_language=\"English\", output_language=\"French\", text=\"I love programming.\")\noutput\n'System: You are a helpful assistant that translates English to French.\\nHuman: I love programming.'\n# or alternatively \noutput_2 = chat_prompt.format_prompt(input_language=\"English\", output_language=\"French\", text=\"I love programming.\").to_string()\nassert output == output_2\nAs ChatPromptValue\nchat_prompt.format_prompt(input_language=\"English\", output_language=\"French\", text=\"I love programming.\")\nChatPromptValue(messages=[SystemMessage(content='You are a helpful assistant that translates English to French.', additional_kwargs={}), HumanMessage(content='I love programming.', additional_kwargs={})])\nAs list of Message objects\nchat_prompt.format_prompt(input_language=\"English\", output_language=\"French\", text=\"I love programming.\").to_messages()", "source": "https://python.langchain.com/en/latest/modules/prompts/chat_prompt_template.html"}

The most commonly used are AIMessagePromptTemplate, SystemMessagePromptTemplate and HumanMessagePromptTemplate, which create an AI message, system message and human message respectively.\nHowever, in cases where the chat model supports taking chat message with arbitrary role, you can use ChatMessagePromptTemplate, which allows user to specify the role name.\nfrom langchain.prompts import ChatMessagePromptTemplate\nprompt = \"May the {subject} be with you\"\nchat_message_prompt = ChatMessagePromptTemplate.from_template(role=\"Jedi\", template=prompt)\nchat_message_prompt.format(subject=\"force\")\nChatMessage(content='May the force be with you', additional_kwargs={}, role='Jedi')\nLangChain also provides MessagesPlaceholder, which gives you full control of what messages to be rendered during formatting.

For more on this, see here.\nThis concept is extremely relevant when considering putting LLM applications in production. In order to personalize LLM applications, you may want to combine LLMs with up-to-date information about particular users. Feature stores can be a great way to keep that data fresh, and LangChain provides an easy way to combine that data with LLMs.\nIn this notebook we will show how to connect prompt templates to feature stores. The basic idea is to call a feature store from inside a prompt template to retrieve values that are then formatted into the prompt.\nFeast#\nTo start, we will use the popular open source feature store framework Feast.\nThis assumes you have already run the steps in the README around getting started. We will build of off that example in getting started, and create and LLMChain to write a note to a specific driver regarding their up-to-date statistics.\nLoad Feast Store#\nAgain, this should be set up according to the instructions in the Feast README\nfrom feast import FeatureStore\n# You may need to update the path depending on where you stored it\nfeast_repo_path = \"../../../../../my_feature_repo/feature_repo/\"\nstore = FeatureStore(repo_path=feast_repo_path)\nPrompts#\nHere we will set up a custom FeastPromptTemplate.

This can make it easy to share, store, and version prompts. This notebook covers how to do that in LangChain, walking through all the different types of prompts and the different serialization options.\nAt a high level, the following design principles are applied to serialization:\nBoth JSON and YAML are supported. We want to support serialization methods that are human readable on disk, and YAML and JSON are two of the most popular methods for that. Note that this rule applies to prompts. For other assets, like Examples, different serialization methods may be supported.\nWe support specifying everything in one file, or storing different components (templates, examples, etc) in different files and referencing them. For some cases, storing everything in file makes the most sense, but for others it is preferrable to split up some of the assets (long templates, large examples, reusable components). LangChain supports both.\nThere is also a single entry point to load prompts from disk, making it easy to load any type of prompt.\n# All prompts are loaded through the `load_prompt` function.\nfrom langchain.prompts import load_prompt\nPromptTemplate#\nThis section covers examples for loading a PromptTemplate.\nLoading from YAML#\nThis shows an example of loading a PromptTemplate from YAML.\n!cat simple_prompt.yaml\n_type: prompt\ninput_variables:\n    [\"adjective\", \"content\"]\ntemplate: \n    Tell me a {adjective} joke about {content}.\nprompt = load_prompt(\"simple_prompt.yaml\")", "source": "https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/prompt_serialization.html"}

To achieve this task, we will create a custom prompt template that takes in the function name as input, and formats the prompt template to provide the source code of the function.\nWhy are custom prompt templates needed?#\nLangChain provides a set of default prompt templates that can be used to generate prompts for a variety of tasks. However, there may be cases where the default prompt templates do not meet your needs. For example, you may want to create a prompt template with specific dynamic instructions for your language model. In such cases, you can create a custom prompt template.\nTake a look at the current set of default prompt templates here.\nCreating a Custom Prompt Template#\nThere are essentially two distinct prompt templates available - string prompt templates and chat prompt templates. String prompt templates provides a simple prompt in string format, while chat prompt templates produces a more structured prompt to be used with a chat API.\nIn this guide, we will create a custom prompt using a string prompt template.\nTo create a custom string prompt template, there are two requirements:\nIt has an input_variables attribute that exposes what input variables the prompt template expects.\nIt exposes a format method that takes in keyword arguments corresponding to the expected input_variables and returns the formatted prompt.\nWe will create a custom prompt template that takes in the function name as input and formats the prompt to provide the source code of the function. To achieve this, let\u2019s first create a function that will return the source code of a function given its name.\nimport inspect\ndef get_source_code(function_name):\n    # Get the source code of the function", "source": "https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/custom_prompt_template.html"}

{"id": "650011c4cc74-0", "text": ".ipynb\n.pdf\nHow to work with partial Prompt Templates\n Contents \nPartial With Strings\nPartial With Functions\nHow to work with partial Prompt Templates#\nA prompt template is a class with a .format method which takes in a key-value map and returns a string (a prompt) to pass to the language model. Like other methods, it can make sense to \u201cpartial\u201d a prompt template - eg pass in a subset of the required values, as to create a new prompt template which expects only the remaining subset of values.\nLangChain supports this in two ways: we allow for partially formatted prompts (1) with string values, (2) with functions that return string values. These two different ways support different use cases. In the documentation below we go over the motivations for both use cases as well as how to do it in LangChain.\nPartial With Strings#\nOne common use case for wanting to partial a prompt template is if you get some of the variables before others. For example, suppose you have a prompt template that requires two variables, foo and baz. If you get the foo value early on in the chain, but the baz value later, it can be annoying to wait until you have both variables in the same place to pass them to the prompt template. Instead, you can partial the prompt template with the foo value, and then pass the partialed prompt template along and just use that. Below is an example of doing this:\nfrom langchain.prompts import PromptTemplate\nprompt = PromptTemplate(template=\"{foo}{bar}\", input_variables=[\"foo\", \"bar\"])\npartial_prompt = prompt.partial(foo=\"foo\");\nprint(partial_prompt.format(bar=\"baz\"))\nfoobaz\nYou can also just initialize the prompt with the partialed variables.\nprompt = PromptTemplate(template=\"{foo}{bar}\", input_variables=[\"bar\"], partial_variables={\"foo\": \"foo\"})\nprint(prompt.format(bar=\"baz\"))\nfoobaz", "source": "https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/partial.html"}
{"id": "650011c4cc74-1", "text": "print(prompt.format(bar=\"baz\"))\nfoobaz\nPartial With Functions#\nThe other common use is to partial with a function. The use case for this is when you have a variable you know that you always want to fetch in a common way. A prime example of this is with date or time. Imagine you have a prompt which you always want to have the current date. You can\u2019t hard code it in the prompt, and passing it along with the other input variables is a bit annoying. In this case, it\u2019s very handy to be able to partial the prompt with a function that always returns the current date.\nfrom datetime import datetime\ndef _get_datetime():\n    now = datetime.now()\n    return now.strftime(\"%m/%d/%Y, %H:%M:%S\")\nprompt = PromptTemplate(\n    template=\"Tell me a {adjective} joke about the day {date}\", \n    input_variables=[\"adjective\", \"date\"]\n);\npartial_prompt = prompt.partial(date=_get_datetime)\nprint(partial_prompt.format(adjective=\"funny\"))\nTell me a funny joke about the day 02/27/2023, 22:15:16\nYou can also just initialize the prompt with the partialed variables, which often makes more sense in this workflow.\nprompt = PromptTemplate(\n    template=\"Tell me a {adjective} joke about the day {date}\", \n    input_variables=[\"adjective\"],\n    partial_variables={\"date\": _get_datetime}\n);\nprint(prompt.format(adjective=\"funny\"))\nTell me a funny joke about the day 02/27/2023, 22:15:16\nprevious\nHow to create a prompt template that uses few shot examples\nnext\nHow to serialize prompts\n Contents\n  \nPartial With Strings\nPartial With Functions\nBy Harrison Chase", "source": "https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/partial.html"}

This is where output parsers come in.\nOutput parsers are classes that help structure language model responses. There are two main methods an output parser must implement:\nget_format_instructions() -> str: A method which returns a string containing instructions for how the output of a language model should be formatted.\nparse(str) -> Any: A method which takes in a string (assumed to be the response from a language model) and parses it into some structure.\nAnd then one optional one:\nparse_with_prompt(str, PromptValue) -> Any: A method which takes in a string (assumed to be the response from a language model) and a prompt (assumed to the prompt that generated such a response) and parses it into some structure. The prompt is largely provided in the event the OutputParser wants to retry or fix the output in some way, and needs information from the prompt to do so.\nBelow we go over the main type of output parser, the PydanticOutputParser. See the examples folder for other options.\nfrom langchain.prompts import PromptTemplate, ChatPromptTemplate, HumanMessagePromptTemplate\nfrom langchain.llms import OpenAI\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.output_parsers import PydanticOutputParser\nfrom pydantic import BaseModel, Field, validator\nfrom typing import List\nmodel_name = 'text-davinci-003'\ntemperature = 0.0\nmodel = OpenAI(model_name=model_name, temperature=temperature)\n# Define your desired data structure.\nclass Joke(BaseModel):\n    setup: str = Field(description=\"question to set up a joke\")\n    punchline: str = Field(description=\"answer to resolve the joke\")", "source": "https://python.langchain.com/en/latest/modules/prompts/output_parsers/getting_started.html"}

There are lots of Embedding providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them.\nEmbeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space.\nThe base Embedding class in LangChain exposes two methods: embed_documents and embed_query. The largest difference is that these two methods have different interfaces: one works over multiple documents, while the other works over a single document. Besides this, another reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself).\nThe following integrations exist for text embeddings.\nAleph Alpha\nAzureOpenAI\nBedrock Embeddings\nCohere\nElasticsearch\nFake Embeddings\nGoogle Cloud Platform Vertex AI PaLM\nHugging Face Hub\nInstructEmbeddings\nJina\nLlama-cpp\nMiniMax\nModelScope\nMosaicML embeddings\nOpenAI\nSageMaker Endpoint Embeddings\nSelf Hosted Embeddings\nSentence Transformers Embeddings\nTensorflowHub\nprevious\nPromptLayer ChatOpenAI\nnext\nAleph Alpha\nBy Harrison Chase\n    \n      \u00a9 Copyright 2023, Harrison Chase.\n      \n  Last updated on Jun 02, 2023.", "source": "https://python.langchain.com/en/latest/modules/models/text_embedding.html"}

This allows you to swap easily between models. At a high level, there are two main types of models:\nLanguage Models: good for text generation\nText Embedding Models: good for turning text into a numerical representation\nLanguage Models#\nThere are two different sub-types of Language Models:\nLLMs: these wrap APIs which take text in and return text\nChatModels: these wrap models which take chat messages in and return a chat message\nThis is a subtle difference, but a value prop of LangChain is that we provide a unified interface accross these. This is nice because although the underlying APIs are actually quite different, you often want to use them interchangeably.\nTo see this, let\u2019s look at OpenAI (a wrapper around OpenAI\u2019s LLM) vs ChatOpenAI (a wrapper around OpenAI\u2019s ChatModel).\nfrom langchain.llms import OpenAI\nfrom langchain.chat_models import ChatOpenAI\nllm = OpenAI()\nchat_model = ChatOpenAI()\ntext -> text interface#\nllm.predict(\"say hi!\")\n'\\n\\nHi there!'\nchat_model.predict(\"say hi!\")\n'Hello there!'\nmessages -> message interface#\nfrom langchain.schema import HumanMessage\nllm.predict_messages([HumanMessage(content=\"say hi!\")])\nAIMessage(content='\\n\\nHello!

This complete response includes things like multiple top responses, as well as LLM provider specific information\nllm_result = llm.generate([\"Tell me a joke\", \"Tell me a poem\"]*15)\nlen(llm_result.generations)\n30\nllm_result.generations[0]\n[Generation(text='\\n\\nWhy did the chicken cross the road?\\n\\nTo get to the other side!'),\n Generation(text='\\n\\nWhy did the chicken cross the road?\\n\\nTo get to the other side.')]\nllm_result.generations[-1]", "source": "https://python.langchain.com/en/latest/modules/models/llms/getting_started.html"}

This information is NOT standardized across providers.\nllm_result.llm_output\n{'token_usage': {'completion_tokens': 3903,\n  'total_tokens': 4023,\n  'prompt_tokens': 120}}\nNumber of Tokens: You can also estimate how many tokens a piece of text will be in that model. This is useful because models have a context length (and cost more for more tokens), which means you need to be aware of how long the text you are passing in is.\nNotice that by default the tokens are estimated using tiktoken (except for legacy version <3.8, where a Hugging Face tokenizer is used)\nllm.get_num_tokens(\"what a joke\")\n3\nprevious\nLLMs\nnext\nGeneric Functionality\nBy Harrison Chase\n    \n      \u00a9 Copyright 2023, Harrison Chase.", "source": "https://python.langchain.com/en/latest/modules/models/llms/getting_started.html"}

The openai Python package makes it easy to use both OpenAI and Azure OpenAI.  You can call Azure OpenAI the same way you call OpenAI with the exceptions noted below.\nAPI configuration#\nYou can configure the openai package to use Azure OpenAI using environment variables.  The following is for bash:\n# Set this to `azure`\nexport OPENAI_API_TYPE=azure\n# The API version you want to use: set this to `2022-12-01` for the released version.\nexport OPENAI_API_VERSION=2022-12-01\n# The base URL for your Azure OpenAI resource.

When calling the API, you need to specify the deployment you want to use.\nLet\u2019s say your deployment name is text-davinci-002-prod.  In the openai Python API, you can specify this deployment with the engine parameter.

And worst of all, so much loss of life.\" He said the CDC is working on a vaccine for kids under 5, and that the government will be ready with plenty of vaccines when they are available. Obama says the new guidelines are a \"great step forward\" and that the virus is no longer a threat. He says the government is launching a \"Test to Treat\" initiative that will allow people to get tested at a pharmacy and get antiviral pills on the spot at no cost.

The response will be a message. The types of messages currently supported in LangChain are AIMessage, HumanMessage, SystemMessage, and ChatMessage \u2013 ChatMessage takes in an arbitrary role parameter. Most of the time, you\u2019ll just be dealing with HumanMessage, AIMessage, and SystemMessage\nchat([HumanMessage(content=\"Translate this sentence from English to French. I love programming.\")])\nAIMessage(content=\"J'aime programmer.\", additional_kwargs={})\nOpenAI\u2019s chat model supports multiple messages as input. See here for more information. Here is an example of sending a system and user message to the chat model:\nmessages = [\n    SystemMessage(content=\"You are a helpful assistant that translates English to French.\"),\n    HumanMessage(content=\"I love programming.\")\n]\nchat(messages)\nAIMessage(content=\"J'aime programmer.\", additional_kwargs={})\nYou can go one step further and generate completions for multiple sets of messages using generate.

{"id": "2ec0d7d30348-0", "text": ".ipynb\n.pdf\nGetting Started\n Contents \nOne Line Index Creation\nWalkthrough\nGetting Started#\nLangChain primarily focuses on constructing indexes with the goal of using them as a Retriever. In order to best understand what this means, it\u2019s worth highlighting what the base Retriever interface is. The BaseRetriever class in LangChain is as follows:\nfrom abc import ABC, abstractmethod\nfrom typing import List\nfrom langchain.schema import Document\nclass BaseRetriever(ABC):\n    @abstractmethod\n    def get_relevant_documents(self, query: str) -> List[Document]:\n        \"\"\"Get texts relevant for a query.\n        Args:\n            query: string to find relevant texts for\n        Returns:\n            List of relevant documents\n        \"\"\"\nIt\u2019s that simple! The get_relevant_documents method can be implemented however you see fit.\nOf course, we also help construct what we think useful Retrievers are. The main type of Retriever that we focus on is a Vectorstore retriever. We will focus on that for the rest of this guide.\nIn order to understand what a vectorstore retriever is, it\u2019s important to understand what a Vectorstore is. So let\u2019s look at that.\nBy default, LangChain uses Chroma as the vectorstore to index and search embeddings. To walk through this tutorial, we\u2019ll first need to install chromadb.\npip install chromadb\nThis example showcases question answering over documents.\nWe have chosen this as the example for getting started because it nicely combines a lot of different elements (Text splitters, embeddings, vectorstores) and then also shows how to use them in a chain.\nQuestion answering over documents consists of four steps:\nCreate an index\nCreate a Retriever from that index\nCreate a question answering chain\nAsk questions!", "source": "https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}
{"id": "2ec0d7d30348-1", "text": "Create a Retriever from that index\nCreate a question answering chain\nAsk questions!\nEach of the steps has multiple sub steps and potential configurations. In this notebook we will primarily focus on (1). We will start by showing the one-liner for doing so, but then break down what is actually going on.\nFirst, let\u2019s import some common classes we\u2019ll use no matter what.\nfrom langchain.chains import RetrievalQA\nfrom langchain.llms import OpenAI\nNext in the generic setup, let\u2019s specify the document loader we want to use.

Data will be transient.\nNow that the index is created, we can use it to ask questions of the data! Note that under the hood this is actually doing a few steps as well, which we will cover later in this guide.\nquery = \"What did the president say about Ketanji Brown Jackson\"\nindex.query(query)\n\" The president said that Ketanji Brown Jackson is one of the nation's top legal minds, a former top litigator in private practice, a former federal public defender, and from a family of public school educators and police officers. He also said that she is a consensus builder and has received a broad range of support from the Fraternal Order of Police to former judges appointed by Democrats and Republicans.\"\nquery = \"What did the president say about Ketanji Brown Jackson\"\nindex.query_with_sources(query)", "source": "https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}

How is this index getting created?\nA lot of the magic is being hid in this VectorstoreIndexCreator. What is this doing?\nThere are three main steps going on after the documents are loaded:\nSplitting documents into chunks\nCreating embeddings for each document\nStoring documents and embeddings in a vectorstore\nLet\u2019s walk through this in code\ndocuments = loader.load()\nNext, we will split the documents into chunks.\nfrom langchain.text_splitter import CharacterTextSplitter\ntext_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\ntexts = text_splitter.split_documents(documents)\nWe will then select which embeddings we want to use.", "source": "https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}

It is configurable in the text splitter it uses, the embeddings it uses, and the vectorstore it uses. For example, you can configure it as below:\nindex_creator = VectorstoreIndexCreator(\n    vectorstore_cls=Chroma, \n    embedding=OpenAIEmbeddings(),\n    text_splitter=CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\n)", "source": "https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}

Connect the Integration to the Database\n4. Get the Database ID\nUsage\nNotion DB 2/2#\nNotion is a collaboration platform with modified Markdown support that integrates kanban boards, tasks, wikis and databases. It is an all-in-one workspace for notetaking, knowledge and data management, and project and task management.\nNotionDBLoader is a Python class for loading content from a Notion database. It retrieves pages from the database, reads their content, and returns a list of Document objects.\nRequirements#\nA Notion Database\nNotion Integration Token\nSetup#\n1. Create a Notion Table Database#\nCreate a new table database in Notion. You can add any column to the database and they will be treated as metadata. For example you can add the following columns:\nTitle: set Title as the default property.\nCategories: A Multi-select property to store categories associated with the page.\nKeywords: A Multi-select property to store keywords associated with the page.\nAdd your content to the body of each page in the database. The NotionDBLoader will extract the content and metadata from these pages.\n2. Create a Notion Integration#\nTo create a Notion Integration, follow these steps:\nVisit the Notion Developers page and log in with your Notion account.\nClick on the \u201c+ New integration\u201d button.\nGive your integration a name and choose the workspace where your database is located.\nSelect the require capabilities, this extension only need the Read content capability\nClick the \u201cSubmit\u201d button to create the integration.", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/notiondb.html"}

Copy this token and keep it safe, as you\u2019ll need it to use the NotionDBLoader.\n3. Connect the Integration to the Database#\nTo connect your integration to the database, follow these steps:\nOpen your database in Notion.\nClick on the three-dot menu icon in the top right corner of the database view.\nClick on the \u201c+ New integration\u201d button.\nFind your integration, you may need to start typing its name in the search box.\nClick on the \u201cConnect\u201d button to connect the integration to the database.\n4. Get the Database ID#\nTo get the database ID, follow these steps:\nOpen your database in Notion.\nClick on the three-dot menu icon in the top right corner of the database view.\nSelect \u201cCopy link\u201d from the menu to copy the database URL to your clipboard.\nThe database ID is the long string of alphanumeric characters found in the URL. It typically looks like this: https://www.notion.so/username/8935f9d140a04f95a872520c4f123456?v=\u2026. In this example, the database ID is 8935f9d140a04f95a872520c4f123456.\nWith the database properly set up and the integration token and database ID in hand, you can now use the NotionDBLoader code to load content and metadata from your Notion database.\nUsage#\nNotionDBLoader is part of the langchain package\u2019s document loaders.

LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\\nChat: Chat models are a variation on Language Models that expose a different API - rather than working with raw text, they work with messages.

We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\\n\\nBe data-aware: connect a language model to other sources of data\\nBe agentic: allow a language model to interact with its environment\\n\\nThe LangChain framework is designed with the above principles in mind.\\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here.

LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\\n\\n\\n\\n\\n\\nUse Cases#\\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\\n\\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\\nChatbots: Since language models are good at producing text, that makes them", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/sitemap.html"}

I also heard that at first it was seized by U.S. customs if it ever tried to enter this country, therefore being a fan of films considered \"controversial\" I really had to see this for myself.<br /><br />The plot is centered around a young Swedish drama student named Lena who wants to learn everything she can about life. In particular she wants to focus her attentions to making some sort of documentary on what the average Swede thought about certain political issues such as the Vietnam War and race issues in the United States. In between asking politicians and ordinary denizens of Stockholm about their opinions on politics, she has sex with her drama teacher, classmates, and married men.<br /><br />What kills me about I AM CURIOUS-YELLOW is that 40 years ago, this was considered pornographic. Really, the sex and nudity scenes are few and far between, even then it\\'s not shot like some cheaply made porno. While my countrymen mind find it shocking, in reality sex and nudity are a major staple in Swedish cinema. Even Ingmar Bergman, arguably their answer to good old boy John Ford, had sex scenes in his films.<br /><br />I do commend the filmmakers for the fact that any sex shown in the film is shown for artistic purposes rather than just to shock people and make money to be shown in pornographic theaters in America. I AM CURIOUS-YELLOW is a good film for anyone wanting to study the meat and potatoes (no pun intended) of Swedish cinema.

I\\'ve seen R-rated films with male nudity. Granted, they only offer some fleeting views, but where are the R-rated films with gaping vulvas and flapping labia? Nowhere, because they don\\'t exist.

LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done.

Personal assistants need to take actions, remember interactions, and have knowledge about your data.\\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\\nExtraction: Extract structured information from text.\\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information.

We believe that the most powerful and differentiated applications will not only call out to a language model, but will also be:\n1. _Data-aware_: connect a language model to other sources of data\n2. _Agentic_: allow a language model to interact with its environment\nThe LangChain framework is designed around these principles.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see [here](https://docs.langchain.com/docs/). For the JavaScript documentation, see [here](https://js.langchain.com/docs/).\n## Getting Started [\\#](\\#getting-started \"Permalink to this headline\")\nHow to get started using LangChain to create an Language Model application.\n- [Quickstart Guide](https://python.langchain.com/en/latest/getting_started/getting_started.html)\nConcepts and terminology.", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/tomarkdown.html"}

LanghChain also provides external integrations and even end-to-end implementations for off-the-shelf use.\nThe docs for each module contain quickstart examples, how-to guides, reference docs, and conceptual guides.\nThe modules are (from least to most complex):\n- [Models](https://python.langchain.com/en/latest/modules/models.html): Supported model types and integrations.\n- [Prompts](https://python.langchain.com/en/latest/modules/prompts.html): Prompt management, optimization, and serialization.\n- [Memory](https://python.langchain.com/en/latest/modules/memory.html): Memory refers to state that is persisted between calls of a chain/agent.\n- [Indexes](https://python.langchain.com/en/latest/modules/indexes.html): Language models become much more powerful when combined with application-specific data - this module contains interfaces and integrations for loading, querying and updating external data.\n- [Chains](https://python.langchain.com/en/latest/modules/chains.html): Chains are structured sequences of calls (to an LLM or to a different utility).\n- [Agents](https://python.langchain.com/en/latest/modules/agents.html): An agent is a Chain in which an LLM, given a high-level directive and a set of tools, repeatedly decides an action, executes the action and observes the outcome until the high-level directive is complete.", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/tomarkdown.html"}

Examples include AutoGPT and BabyAGI.\n- [Agent Simulations](https://python.langchain.com/en/latest/use_cases/agent_simulations.html): Putting agents in a sandbox and observing how they interact with each other and react to events can be an effective way to evaluate their long-range reasoning and planning abilities.\n- [Personal Assistants](https://python.langchain.com/en/latest/use_cases/personal_assistants.html): One of the primary LangChain use cases. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\n- [Question Answering](https://python.langchain.com/en/latest/use_cases/question_answering.html): Another common LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\n- [Chatbots](https://python.langchain.com/en/latest/use_cases/chatbots.html): Language models love to chat, making this a very natural use of them.\n- [Querying Tabular Data](https://python.langchain.com/en/latest/use_cases/tabular.html): Recommended reading if you want to use language models to query structured data (CSVs, SQL, dataframes, etc).", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/tomarkdown.html"}

If you bought it from Apple or from an official retailer like Carphone warehouse etc. Then you\\'ll have a year warranty and can get it replaced free.\\nIf you bought it second hand, from a third part repair shop or online, then it may still have warranty, unless it is refurbished and has been repaired elsewhere.\\nIf this is the case, it may be the screen that needs replacing to solve your issue.\\nEither way, wherever you got it, it\\'s best to return it and get a refund or a replacement device. :-)\\n\\n\\n\\n### Most Helpful Answer\\nI had the same issues, screen freezing, opening apps by itself, selecting the screens and typing on it\\'s own.

Two weeks ago, I changed my iPhone 6 Plus shell (I had forced the phone into it because it\u2019s pretty tight), and also put a new glass screen protector (the edges of the protector don\u2019t stick to the screen, weird, so I brushed pressure on the edges at times to see if they may smooth out one day miraculously).  I\u2019m not sure if I accidentally bend the phone when I installed the shell,  or, if I got a defective glass protector that messes up the touch sensor. Well, yesterday was the worse day, keeps dropping calls and ghost pressing keys for me when I was on a call.  I got fed up, so I removed the screen protector, and so far problems have not reoccurred yet. I\u2019m crossing my fingers that problems indeed solved.\\n\\n\\n\\n### Other Answer\\nthank you so much for this post! i was struggling doing the reset because i cannot type userids and passwords correctly because the iphone 6 plus i have kept on typing letters incorrectly.

Then I turned on and it worked.\\n\\n\\n\\n### Other Answer\\nI think at& t should man up and fix your phone for free!  You pay a lot for a Apple they should back it.  I did the next 30 month payments and finally have it paid off in June.  My iPad sept.  Looking forward to a almost 100 drop in my phone bill!  Now this crap!!! Really\\n\\n\\n\\n### Other Answer\\nIf your phone is JailBroken, suggest downloading a virus.  While all my symptoms were similar, there was indeed a virus/malware on the phone which allowed for remote control of my iphone (even while in lock mode).  My mistake for buying a third party iphone i suppose.  Anyway i have since had the phone restored to factory and everything is working as expected for now.  I will of course keep you posted if this changes.  Thanks to all for the helpful posts, really helped me narrow a few things down.\\n\\n\\n\\n### Other Answer\\nWhen my phone was doing this, it ended up being the screen protector that i got from 5 below.

It does this by simultaneously providing a card tokenization/vault service as well as a gateway and receiver integration service. Payment methods tokenized by Spreedly are stored at Spreedly, allowing you to independently store a card and then pass that card to different end points based on your business requirements.\nThis notebook covers how to load data from the Spreedly REST API into a format that can be ingested into LangChain, along with example usage for vectorization.\nNote: this notebook assumes the following packages are installed: openai, chromadb, and tiktoken.\nimport os\nfrom langchain.document_loaders import SpreedlyLoader\nfrom langchain.indexes import VectorstoreIndexCreator\nSpreedly API requires an access token, which can be found inside the Spreedly Admin Console.\nThis document loader does not currently support pagination, nor access to more complex objects which require additional parameters. It also requires a resource option which defines what objects you want to load.\nFollowing resources are available:\ngateways_options: Documentation\ngateways: Documentation\nreceivers_options: Documentation\nreceivers: Documentation\npayment_methods: Documentation\ncertificates: Documentation\ntransactions: Documentation\nenvironments: Documentation\nspreedly_loader = SpreedlyLoader(os.environ[\"SPREEDLY_ACCESS_TOKEN\"], \"gateways_options\")\n# Create a vectorstore retriver from the loader\n# see https://python.langchain.com/en/latest/modules/indexes/getting_started.html for more details\nindex = VectorstoreIndexCreator().from_loaders([spreedly_loader])\nspreedly_doc_retriever = index.vectorstore.as_retriever()\nUsing embedded DuckDB without persistence: data will be transient", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/spreedly.html"}

It provides the advantages of using this system over alternative data loaders.\nPrerequisites#\nInstall necessary python packages.\nGrab an access token for your workspace, and make sure it is set as the DOCUGAMI_API_KEY environment variable.\nGrab some docset and document IDs for your processed documents, as described here: https://help.docugami.com/home/docugami-api\n# You need the lxml package to use the DocugamiLoader\n!pip install lxml\nQuick start#\nCreate a Docugami workspace (free trials available)\nAdd your documents (PDF, DOCX or DOC) and allow Docugami to ingest and cluster them into sets of similar documents, e.g. NDAs, Lease Agreements, and Service Agreements. There is no fixed set of document types supported by the system, the clusters created depend on your particular documents, and you can change the docset assignments later.\nCreate an access token via the Developer Playground for your workspace. Detailed instructions\nExplore the Docugami API to get a list of your processed docset IDs, or just the document IDs for a particular docset.\nUse the DocugamiLoader as detailed below, to get rich semantic chunks for your documents.\nOptionally, build and publish one or more reports or abstracts. This helps Docugami improve the semantic XML with better tags based on your preferences, which are then added to the DocugamiLoader output as metadata. Use techniques like self-querying retriever to do high accuracy Document QA.\nAdvantages vs Other Chunking Techniques#", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/docugami.html"}
{"id": "8f5aa8608be3-1", "text": "Advantages vs Other Chunking Techniques#\nAppropriate chunking of your documents is critical for retrieval from documents. Many chunking techniques exist, including simple ones that rely on whitespace and recursive chunk splitting based on character length. Docugami offers a different approach:\nIntelligent Chunking: Docugami breaks down every document into a hierarchical semantic XML tree of chunks of varying sizes, from single words or numerical values to entire sections. These chunks follow the semantic contours of the document, providing a more meaningful representation than arbitrary length or simple whitespace-based chunking.\nStructured Representation: In addition, the XML tree indicates the structural contours of every document, using attributes denoting headings, paragraphs, lists, tables, and other common elements, and does that consistently across all supported document formats, such as scanned PDFs or DOCX files. It appropriately handles long-form document characteristics like page headers/footers or multi-column flows for clean text extraction.\nSemantic Annotations: Chunks are annotated with semantic tags that are coherent across the document set, facilitating consistent hierarchical queries across multiple documents, even if they are written and formatted differently. For example, in set of lease agreements, you can easily identify key provisions like the Landlord, Tenant, or Renewal Date, as well as more complex information such as the wording of any sub-lease provision or whether a specific jurisdiction has an exception section within a Termination Clause.\nAdditional Metadata: Chunks are also annotated with additional metadata, if a user has been using Docugami. This additional metadata can be used for high-accuracy Document QA without context window restrictions. See detailed code walk-through below.\nimport os\nfrom langchain.document_loaders import DocugamiLoader\nLoad Documents#\nIf the DOCUGAMI_API_KEY environment variable is set, there is no need to pass it in to the loader explicitly otherwise you can pass it in as the access_token parameter.", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/docugami.html"}

{"id": "8f5aa8608be3-21", "text": "Using Docugami to Add Metadata to Chunks for High Accuracy Document QA#\nOne issue with large documents is that the correct answer to your question may depend on chunks that are far apart in the document. Typical chunking techniques, even with overlap, will struggle with providing the LLM sufficent context to answer such questions. With upcoming very large context LLMs, it may be possible to stuff a lot of tokens, perhaps even entire documents, inside the context but this will still hit limits at some point with very long documents, or a lot of documents.\nFor example, if we ask a more complex question that requires the LLM to draw on chunks from different parts of the document, even OpenAI\u2019s powerful LLM is unable to answer correctly.\nchain_response = qa_chain(\"What is rentable area for the property owned by DHA Group?\")\nchain_response[\"result\"]  # the correct answer should be 13,500\n' 9,753 square feet'\nAt first glance the answer may seem reasonable, but if you review the source chunks carefully for this answer, you will see that the chunking of the document did not end up putting the Landlord name and the rentable area in the same context, since they are far apart in the document. The retriever therefore ends up finding unrelated chunks from other documents not even related to the Menlo Group landlord. That landlord happens to be mentioned on the first page of the file Shorebucks LLC_NJ.pdf file, and while one of the source chunks used by the chain is indeed from that doc that contains the correct answer (13,500), other source chunks from different docs are included, and the answer is therefore incorrect.\nchain_response[\"source_documents\"]", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/docugami.html"}

Currently supported strategies are \"hi_res\" (the default) and \"fast\". Hi res partitioning strategies are more accurate, but take longer to process. Fast strategies partition the document more quickly, but trade-off accuracy. Not all document types have separate hi res and fast partitioning strategies. For those document types, the strategy kwarg is ignored. In some cases, the high res strategy will fallback to fast if there is a dependency missing (i.e. a model for document partitioning). You can see how to apply a strategy to an UnstructuredFileLoader below.\nfrom langchain.document_loaders import UnstructuredFileLoader", "source": "https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/unstructured_file.html"}

It makes it useful for all sorts of neural network or semantic-based matching, faceted search, and other applications.\nThis notebook shows how to use functionality related to the Qdrant vector database.\nThere are various modes of how to run Qdrant, and depending on the chosen one, there will be some subtle differences.

That\u2019s great for testing things out and debugging or if you plan to store just a small amount of vectors. The embeddings might be fully kepy in memory or persisted on disk.\nIn-memory#\nFor some testing scenarios and quick experiments, you may prefer to keep all the data in memory only, so it gets lost when the client is destroyed - usually at the end of your script/notebook.\nqdrant = Qdrant.from_documents(\n    docs, embeddings, \n    location=\":memory:\",  # Local mode with in-memory storage only\n    collection_name=\"my_documents\",\n)\nOn-disk storage#\nLocal mode, without using the Qdrant server, may also store your vectors on disk so they\u2019re persisted between runs.\nqdrant = Qdrant.from_documents(\n    docs, embeddings, \n    path=\"/tmp/local_qdrant\",\n    collection_name=\"my_documents\",\n)\nOn-premise server deployment#\nNo matter if you choose to launch Qdrant locally with a Docker container, or select a Kubernetes deployment with the official Helm chart, the way you\u2019re going to connect to such an instance will be identical.

This feature is in early access and available only for evaluation purposes, to validate functionality, and to gather feedback from a small closed group of early access users. It is not recommended for production deployments as we may introduce breaking changes.\nTo use MongoDB Atlas, you must have first deployed a cluster. Free clusters are available.\nHere is the MongoDB Atlas quick start.\n!pip install pymongo\nimport os\nMONGODB_ATLAS_URI = os.environ['MONGODB_ATLAS_URI']\nWe want to use OpenAIEmbeddings so we have to get the OpenAI API Key.

This text splitter takes a list of characters. It tries to create chunks based on splitting on the first character, but if any chunks are too large it then moves onto the next character, and so forth. By default the characters it tries to split on are [\"\\n\\n\", \"\\n\", \" \", \"\"]\nIn addition to controlling which characters you can split on, you can also control a few other things:\nlength_function: how the length of chunks is calculated. Defaults to just counting number of characters, but it\u2019s pretty common to pass a token counter here.\nchunk_size: the maximum size of your chunks (as measured by the length function).\nchunk_overlap: the maximum overlap between chunks. It can be nice to have some overlap to maintain some continuity between chunks (eg do a sliding window).\n# This is a long document we can split up.\nwith open('../../state_of_the_union.txt') as f:\n    state_of_the_union = f.read()\nfrom langchain.text_splitter import RecursiveCharacterTextSplitter\ntext_splitter = RecursiveCharacterTextSplitter(\n    # Set a really small chunk size, just to show.\n    chunk_size = 100,\n    chunk_overlap  = 20,\n    length_function = len,\n)\ntexts = text_splitter.create_documents([state_of_the_union])\nprint(texts[0])\nprint(texts[1])\npage_content='Madam Speaker, Madam Vice President, our First Lady and Second Gentleman.

The approach uses the binding property of images to align each modality's embedding to image embeddings and achieve an emergent alignment across all modalities. This enables novel multimodal capabilities, including cross-modal retrieval, embedding-space arithmetic, and audio-to-image generation, among others. The approach sets a new state-of-the-art on emergent zero-shot recognition tasks across modalities, outperforming specialist supervised models. Additionally, it shows strong few-shot recognition results and serves as a new way to evaluate vision models for visual and non-visual tasks. \n-> **Question**: How does Compositional Reasoning with Large Language Models works?", "source": "https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/arxiv.html"}
{"id": "e5f8fc12f635-3", "text": "-> **Question**: How does Compositional Reasoning with Large Language Models works? \n**Answer**: Compositional reasoning with large language models refers to the ability of these models to correctly identify and represent complex concepts by breaking them down into smaller, more basic parts and combining them in a structured way. This involves understanding the syntax and semantics of language and using that understanding to build up more complex meanings from simpler ones. \nIn the context of the paper \"Does CLIP Bind Concepts? Probing Compositionality in Large Image Models\", the authors focus specifically on the ability of a large pretrained vision and language model (CLIP) to encode compositional concepts and to bind variables in a structure-sensitive way. They examine CLIP's ability to compose concepts in a single-object setting, as well as in situations where concept binding is needed. \nThe authors situate their work within the tradition of research on compositional distributional semantics models (CDSMs), which seek to bridge the gap between distributional models and formal semantics by building architectures which operate over vectors yet still obey traditional theories of linguistic composition. They compare the performance of CLIP with several architectures from research on CDSMs to evaluate its ability to encode and reason about compositional concepts. \nquestions = [\n    \"What are Heat-bath random walks with Markov base?

{"id": "e5f8fc12f635-4", "text": "**Answer**: Heat-bath random walks with Markov base (HB-MB) is a class of stochastic processes that have been studied in the field of statistical mechanics and condensed matter physics. In these processes, a particle moves in a lattice by making a transition to a neighboring site, which is chosen according to a probability distribution that depends on the energy of the particle and the energy of its surroundings.\nThe HB-MB process was introduced by Bortz, Kalos, and Lebowitz in 1975 as a way to simulate the dynamics of interacting particles in a lattice at thermal equilibrium. The method has been used to study a variety of physical phenomena, including phase transitions, critical behavior, and transport properties.\nReferences:\nBortz, A. B., Kalos, M. H., & Lebowitz, J.

Specifically, given any natural language query, the retriever uses a query-constructing LLM chain to write a structured query and then applies that structured query to it\u2019s underlying VectorStore. This allows the retriever to not only use the user-input query for semantic similarity comparison with the contents of stored documented, but to also extract filters from the user query on the metadata of stored documents and to execute those filters.\nCreating a Pinecone index#\nFirst we\u2019ll want to create a Pinecone VectorStore and seed it with some data.

It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents.\nIn information retrieval, Okapi BM25 (BM is an abbreviation of best matching) is a ranking function used by search engines to estimate the relevance of documents to a given search query. It is based on the probabilistic retrieval framework developed in the 1970s and 1980s by Stephen E. Robertson, Karen Sp\u00e4rck Jones, and others.\nThe name of the actual ranking function is BM25. The fuller name, Okapi BM25, includes the name of the first system to use it, which was the Okapi information retrieval system, implemented at London\u2019s City University in the 1980s and 1990s. BM25 and its newer variants, e.g. BM25F (a version of BM25 that can take document structure and anchor text into account), represent TF-IDF-like retrieval functions used in document retrieval.\nThis notebook shows how to use a retriever that uses ElasticSearch and BM25.\nFor more information on the details of BM25 see this blog post.\n#!pip install elasticsearch\nfrom langchain.retrievers import ElasticSearchBM25Retriever\nCreate New Retriever#\nelasticsearch_url=\"http://localhost:9200\"\nretriever = ElasticSearchBM25Retriever.create(elasticsearch_url, \"langchain-index-4\")\n# Alternatively, you can load an existing index\n# import elasticsearch\n# elasticsearch_url=\"http://localhost:9200\"", "source": "https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/elastic_search_bm25.html"}

The story focuses on a young boy named Gon Freecss who discovers that his father, who left him at a young age, is actually a world-renowned Hunter, a licensed professional who specializes in fantastical pursuits such as locating rare or unidentified animal species, treasure hunting, surveying unexplored enclaves, or hunting down lawless individuals. Gon departs on a journey to become a Hunter and eventually find his father. Along the way, Gon meets various other Hunters and encounters the paranormal.\\nHunter \u00d7 Hunter was adapted into a 62-episode anime television series produced by Nippon Animation and directed by Kazuhiro Furuhashi, which ran on Fuji Television from October 1999 to March 2001. Three separate original video animations (OVAs) totaling 30 episodes were subsequently produced by Nippon Animation and released in Japan from 2002 to 2004. A second anime television series by Madhouse aired on Nippon Television from October 2011 to September 2014, totaling 148 episodes, with two animated theatrical films released in 2013. There are also numerous audio albums, video games, musicals, and other media based on Hunter \u00d7 Hunter.\\nThe manga has been translated into English and released in North America by Viz Media since April 2005.

The purpose of this notebook is to show you how to easily use agents through the simplest, highest level API.\nIn order to load agents, you should understand the following concepts:\nTool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.\nLLM: The language model powering the agent.\nAgent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents.

Then we feed the documents into a vector index and answer questions from it.\n#!pip install apify-client\nFirst, import ApifyWrapper into your source code:\nfrom langchain.document_loaders.base import Document\nfrom langchain.indexes import VectorstoreIndexCreator\nfrom langchain.utilities import ApifyWrapper\nInitialize it using your Apify API token and for the purpose of this example, also with your OpenAI API key:\nimport os\nos.environ[\"OPENAI_API_KEY\"] = \"Your OpenAI API key\"\nos.environ[\"APIFY_API_TOKEN\"] = \"Your Apify API token\"\napify = ApifyWrapper()\nThen run the Actor, wait for it to finish, and fetch its results from the Apify dataset into a LangChain document loader.\nNote that if you already have some results in an Apify dataset, you can load them directly using ApifyDatasetLoader, as shown in this notebook. In that notebook, you\u2019ll also find the explanation of the dataset_mapping_function, which is used to map fields from the Apify dataset records to LangChain Document fields.\nloader = apify.call_actor(\n    actor_id=\"apify/website-content-crawler\",", "source": "https://python.langchain.com/en/latest/modules/agents/tools/examples/apify.html"}

Review full docs or reach out to nla@zapier.com for user-facing oauth developer support.\nThis example goes over how to use the Zapier integration with a SimpleSequentialChain, then an Agent.\nIn code, below:\nimport os\n# get from https://platform.openai.com/\nos.environ[\"OPENAI_API_KEY\"] = os.environ.get(\"OPENAI_API_KEY\", \"\")", "source": "https://python.langchain.com/en/latest/modules/agents/tools/examples/zapier.html"}

Its chapters have been collected in 37 tank\u014dbon volumes as of November 2022. The story focuses on a young boy named Gon Freecss who discovers that his father, who left him at a young age, is actually a world-renowned Hunter, a licensed professional who specializes in fantastical pursuits such as locating rare or unidentified animal species, treasure hunting, surveying unexplored enclaves, or hunting down lawless individuals. Gon departs on a journey to become a Hunter and eventually find his father. Along the way, Gon meets various other Hunters and encounters the paranormal.\\nHunter \u00d7 Hunter was adapted into a 62-episode anime television series produced by Nippon Animation and directed by Kazuhiro Furuhashi, which ran on Fuji Television from October 1999 to March 2001. Three separate original video animations (OVAs) totaling 30 episodes were subsequently produced by Nippon Animation and released in Japan from 2002 to 2004. A second anime television series by Madhouse aired on Nippon Television from October 2011 to September 2014, totaling 148 episodes, with two animated theatrical films released in 2013. There are also numerous audio albums, video games, musicals, and other media based on Hunter \u00d7 Hunter.\\nThe manga has been translated into English and released in North America by Viz Media since April 2005.

The use case for this is that you\u2019ve ingested your data into a vectorstore and want to interact with it in an agentic manner.\nThe recommended method for doing so is to create a RetrievalQA and then use that as a tool in the overall agent. Let\u2019s take a look at doing this below. You can do this with multiple different vectordbs, and use the agent as a way to route between them. There are two different ways of doing this - you can either let the agent use the vectorstores as normal tools, or you can set return_direct=True to really just use the agent as a router.\nCreate the Vectorstore#\nfrom langchain.embeddings.openai import OpenAIEmbeddings\nfrom langchain.vectorstores import Chroma\nfrom langchain.text_splitter import CharacterTextSplitter\nfrom langchain.llms import OpenAI\nfrom langchain.chains import RetrievalQA\nllm = OpenAI(temperature=0)\nfrom pathlib import Path\nrelevant_parts = []\nfor p in Path(\".\").absolute().parts:\n    relevant_parts.append(p)\n    if relevant_parts[-3:] == [\"langchain\", \"docs\", \"modules\"]:\n        break\ndoc_path = str(Path(*relevant_parts) / \"state_of_the_union.txt\")\nfrom langchain.document_loaders import TextLoader\nloader = TextLoader(doc_path)\ndocuments = loader.load()\ntext_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\ntexts = text_splitter.split_documents(documents)\nembeddings = OpenAIEmbeddings()", "source": "https://python.langchain.com/en/latest/modules/agents/agent_executors/examples/agent_vectorstore.html"}

We\u2019ll see it\u2019s a viable approach to start working with a massive API spec AND to assist with user queries that require multiple steps against the API.\nThe idea is simple: to get coherent agent behavior over long sequences behavior & to save on tokens, we\u2019ll separate concerns: a \u201cplanner\u201d will be responsible for what endpoints to call and a \u201ccontroller\u201d will be responsible for how to call them.\nIn the initial implementation, the planner is an LLM chain that has the name and a short description for each endpoint in context.

This is the simplest way to create a custom Agent. It is highly recommended that you work with the ZeroShotAgent, as at the moment that is by far the most generalizable one.\nMost of the work in creating the custom LLMChain comes down to the prompt. Because we are using an existing agent class to parse the output, it is very important that the prompt say to produce text in that format. Additionally, we currently require an agent_scratchpad input variable to put notes on previous actions and observations. This should almost always be the final part of the prompt. However, besides those instructions, you can customize the prompt as you wish.\nTo ensure that the prompt contains the appropriate instructions, we will utilize a helper method on that class. The helper method for the ZeroShotAgent takes the following arguments:\ntools: List of tools the agent will have access to, used to format the prompt.\nprefix: String to put before the list of tools.\nsuffix: String to put after the list of tools.\ninput_variables: List of input variables the final prompt will expect.", "source": "https://python.langchain.com/en/latest/modules/agents/agents/custom_mrkl_agent.html"}
