|
### About GGUF |
|
|
|
GGUF is a new format introduced by the llama.cpp team on August 21st 2023. It is a replacement for GGML, which is no longer supported by llama.cpp. |
|
|
|
Here is an incomplate list of clients and libraries that are known to support GGUF: |
|
|
|
* [llama.cpp](https://github.com/ggerganov/llama.cpp). The source project for GGUF. Offers a CLI and a server option. |
|
* [text-generation-webui](https://github.com/oobabooga/text-generation-webui), the most widely used web UI, with many features and powerful extensions. Supports GPU acceleration. |
|
* [KoboldCpp](https://github.com/LostRuins/koboldcpp), a fully featured web UI, with GPU accel across all platforms and GPU architectures. Especially good for story telling. |
|
* [LM Studio](https://lmstudio.ai/), an easy-to-use and powerful local GUI for Windows and macOS (Silicon), with GPU acceleration. |
|
* [LoLLMS Web UI](https://github.com/ParisNeo/lollms-webui), a great web UI with many interesting and unique features, including a full model library for easy model selection. |
|
* [Faraday.dev](https://faraday.dev/), an attractive and easy to use character-based chat GUI for Windows and macOS (both Silicon and Intel), with GPU acceleration. |
|
* [ctransformers](https://github.com/marella/ctransformers), a Python library with GPU accel, LangChain support, and OpenAI-compatible AI server. |
|
* [llama-cpp-python](https://github.com/abetlen/llama-cpp-python), a Python library with GPU accel, LangChain support, and OpenAI-compatible API server. |
|
* [candle](https://github.com/huggingface/candle), a Rust ML framework with a focus on performance, including GPU support, and ease of use. |

## Compatibility |
|
|
|
These quantised GGUFv2 files are compatible with llama.cpp from August 27th onwards, as of commit [d0cee0d](https://github.com/ggerganov/llama.cpp/commit/d0cee0d36d5be95a0d9088b674dbb27354107221) |
|
|
|
They are also compatible with many third party UIs and libraries - please see the list at the top of this README. |
|
|
|
## Explanation of quantisation methods |
|
<details> |
|
<summary>Click to see details</summary> |
|
|
|
The new methods available are: |
|
* GGML_TYPE_Q2_K - "type-1" 2-bit quantization in super-blocks containing 16 blocks, each block having 16 weight. Block scales and mins are quantized with 4 bits. This ends up effectively using 2.5625 bits per weight (bpw) |
|
* GGML_TYPE_Q3_K - "type-0" 3-bit quantization in super-blocks containing 16 blocks, each block having 16 weights. Scales are quantized with 6 bits. This end up using 3.4375 bpw. |
|
* GGML_TYPE_Q4_K - "type-1" 4-bit quantization in super-blocks containing 8 blocks, each block having 32 weights. Scales and mins are quantized with 6 bits. This ends up using 4.5 bpw. |
|
* GGML_TYPE_Q5_K - "type-1" 5-bit quantization. Same super-block structure as GGML_TYPE_Q4_K resulting in 5.5 bpw |
|
* GGML_TYPE_Q6_K - "type-0" 6-bit quantization. Super-blocks with 16 blocks, each block having 16 weights. Scales are quantized with 8 bits. This ends up using 6.5625 bpw |

|
**Note**: the above RAM figures assume no GPU offloading. If layers are offloaded to the GPU, this will reduce RAM usage and use VRAM instead. |
|
|
|
### Q6_K and Q8_0 files are split and require joining |
|
|
|
**Note:** HF does not support uploading files larger than 50GB. Therefore I have uploaded the Q6_K and Q8_0 files as split files. |
|
|
|
<details> |
|
<summary>Click for instructions regarding Q6_K and Q8_0 files</summary> |
|
|
|
### q6_K |

## How to download GGUF files |
|
|
|
**Note for manual downloaders:** You almost never want to clone the entire repo! Multiple different quantisation formats are provided, and most users only want to pick and download a single file. |
|
|
|
The following clients/libraries will automatically download models for you, providing a list of available models to choose from: |
|
- LM Studio |
|
- LoLLMS Web UI |
|
- Faraday.dev |
|
|
|
### In `text-generation-webui` |
|
|
|
Under Download Model, you can enter the model repo: TheBloke/LongAlpaca-70B-GGUF and below it, a specific filename to download, such as: longalpaca-70b.Q4_K_M.gguf. |
|
|
|
Then click Download. |
|
|
|
### On the command line, including multiple files at once |
|
|
|
I recommend using the `huggingface-hub` Python library: |
|
|
|
```shell |
|
pip3 install huggingface-hub |
|
``` |
|
|
|
Then you can download any individual model file to the current directory, at high speed, with a command like this: |
|
|
|
```shell |
|
huggingface-cli download TheBloke/LongAlpaca-70B-GGUF longalpaca-70b.Q4_K_M.gguf --local-dir . --local-dir-use-symlinks False |
|
``` |
|
|
|
<details> |
|
<summary>More advanced huggingface-cli download usage</summary> |
|
|
|
You can also download multiple files at once with a pattern: |
|
|
|
```shell |
|
huggingface-cli download TheBloke/LongAlpaca-70B-GGUF --local-dir . --local-dir-use-symlinks False --include='*Q4_K*gguf' |
|
``` |
|
|
|
For more documentation on downloading with `huggingface-cli`, please see: [HF -> Hub Python Library -> Download files -> Download from the CLI](https://huggingface.co/docs/huggingface_hub/guides/download#download-from-the-cli). |
|
|
|
To accelerate downloads on fast connections (1Gbit/s or higher), install `hf_transfer`: |
|
|
|
```shell |
|
pip3 install hf_transfer |
|
``` |
|
|
|
And set environment variable `HF_HUB_ENABLE_HF_TRANSFER` to `1`: |
|
|
|
```shell |
|
HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/LongAlpaca-70B-GGUF longalpaca-70b.Q4_K_M.gguf --local-dir . --local-dir-use-symlinks False |
|
``` |
|
|
|
Windows Command Line users: You can set the environment variable by running `set HF_HUB_ENABLE_HF_TRANSFER=1` before the download command. |
|

|
## Example `llama.cpp` command |
|
|
|
Make sure you are using `llama.cpp` from commit [d0cee0d](https://github.com/ggerganov/llama.cpp/commit/d0cee0d36d5be95a0d9088b674dbb27354107221) or later. |
|
|
|
```shell |
|
./main -ngl 32 -m longalpaca-70b.Q4_K_M.gguf --color -c 4096 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "Below is an instruction that describes a task. Write a response that appropriately completes the request.\n\n### Instruction:\n{prompt}\n\n### Response:" |
|
``` |
|
|
|
Change `-ngl 32` to the number of layers to offload to GPU. Remove it if you don't have GPU acceleration. |
|
|
|
Change `-c 4096` to the desired sequence length. For extended sequence models - eg 8K, 16K, 32K - the necessary RoPE scaling parameters are read from the GGUF file and set by llama.cpp automatically. |
|
|
|
If you want to have a chat-style conversation, replace the `-p <PROMPT>` argument with `-i -ins` |
|
|
|
For other parameters and how to use them, please refer to [the llama.cpp documentation](https://github.com/ggerganov/llama.cpp/blob/master/examples/main/README.md) |
|
|
|
## How to run in `text-generation-webui` |
|
|
|
Further instructions here: [text-generation-webui/docs/llama.cpp.md](https://github.com/oobabooga/text-generation-webui/blob/main/docs/llama.cpp.md). |
|
|
|
## How to run from Python code |
|
|
|
You can use GGUF models from Python using the [llama-cpp-python](https://github.com/abetlen/llama-cpp-python) or [ctransformers](https://github.com/marella/ctransformers) libraries. |
|
|
|
### How to load this model in Python code, using ctransformers |
|
|
|
#### First install the package |
|
|
|
Run one of the following commands, according to your system: |
|
|
|
```shell |
|
# Base ctransformers with no GPU acceleration |
|
pip install ctransformers |
|
# Or with CUDA GPU acceleration |
|
pip install ctransformers[cuda] |
|
# Or with AMD ROCm GPU acceleration (Linux only) |
|
CT_HIPBLAS=1 pip install ctransformers --no-binary ctransformers |
|
# Or with Metal GPU acceleration for macOS systems only |
|
CT_METAL=1 pip install ctransformers --no-binary ctransformers |
|
``` |
|
|
|
#### Simple ctransformers example code |
|
|
|
```python |
|
from ctransformers import AutoModelForCausalLM |
|
|
|
# Set gpu_layers to the number of layers to offload to GPU. Set to 0 if no GPU acceleration is available on your system. |
|
llm = AutoModelForCausalLM.from_pretrained("TheBloke/LongAlpaca-70B-GGUF", model_file="longalpaca-70b.Q4_K_M.gguf", model_type="llama", gpu_layers=50) |
|
|
|
print(llm("AI is going to")) |
|
``` |
|
|
|
## How to use with LangChain |
|
|
|
Here are guides on using llama-cpp-python and ctransformers with LangChain: |

## Highlights |
|
1. In LongLoRA approach, The proposed shifted short attention is easy to implement, compatible with Flash-Attention, and is not required during inference. |
|
2. We released all our models, including models from 7B to 70B, context length from 8k to 100k, including [LLaMA2-LongLoRA-7B-100k](https://huggingface.co/Yukang/Llama-2-7b-longlora-100k-ft), [LLaMA2-LongLoRA-13B-64k](https://huggingface.co/Yukang/Llama-2-13b-longlora-64k), and [LLaMA2-LongLoRA-70B-32k](https://huggingface.co/Yukang/Llama-2-70b-longlora-32k). |
|
3. We built up a long-context instruction-following dataset, [LongAlpaca-12k](#longalpaca-data). We released the corresponding [LongAlpaca-7B](https://huggingface.co/Yukang/LongAlpaca-7B), [LongAlpaca-13B](https://huggingface.co/Yukang/LongAlpaca-13B) and [LongAlpaca-70B](https://huggingface.co/Yukang/LongAlpaca-70B) models. To our best knowledge, this is the first open-sourced long-context 70B model. |

## LongAlpaca Data |
|
|
|
LongAlpaca-12k contains 9k long QA data that we collected and 3k short QA sampled from the original [Alpaca data](https://github.com/tatsu-lab/stanford_alpaca/blob/main/alpaca_data.json). This is to avoid the case that the model might degrade at short instruction following. The data we collect contains various types and amounts as the following figure. |
|
|
|
| Data | Short QA | Long QA | Total | Download | |
|
|:---------------|----------|----------|----------|----------| |
|
| LongAlpaca-12k | 3k | 9k | 12k | [Link](https://huggingface.co/datasets/Yukang/LongAlpaca-12k) | |
|
|
|
Following the original Alpaca format, our Long QA data uses the following prompts for fine-tuning: |
|
- `instruction`: `str`, describes the task the model should perform. For example, to answer a question after reading a book section or paper. We vary the contents and questions to make instructions diverse. |
|
- `output`: `str`, the answer to the instruction. |
|
|
|
We did not use the `input` format in the Alpaca format for simplicity. |
|

|
|
|
### Fine-tuning |
|
``` |
|
torchrun --nproc_per_node=8 fine-tune.py \ |
|
--model_name_or_path path_to/Llama-2-7b-hf \ |
|
--bf16 True \ |
|
--output_dir path_to_saving_checkpoints \ |
|
--cache_dir path_to_cache \ |
|
--model_max_length 8192 \ |
|
--use_flash_attn True \ |
|
--low_rank_training False \ |
|
--num_train_epochs 1 \ |
|
--per_device_train_batch_size 1 \ |
|
--per_device_eval_batch_size 2 \ |
|
--gradient_accumulation_steps 8 \ |
|
--evaluation_strategy "no" \ |
|
--save_strategy "steps" \ |
|
--save_steps 1000 \ |
|
--save_total_limit 2 \ |
|
--learning_rate 2e-5 \ |
|
--weight_decay 0.0 \ |
|
--warmup_steps 20 \ |
|
--lr_scheduler_type "constant_with_warmup" \ |
|
--logging_steps 1 \ |
|
--deepspeed "ds_configs/stage2.json" \ |
|
--tf32 True \ |
|
--max_steps 1000 |
|
``` |
|
|
|
- Please remember to change `path_to/Llama-2-7b-hf`, `path_to_saving_checkpoints`, `path_to_cache` to your own directory. |
|
- Note that you can change `model_max_length` to other values. |
|
- You could change `ds_configs/stage2.json` to `ds_configs/stage3.json` if you want. |
|
- Please set `use_flash_attn` as `False` if you use V100 machines or do not install flash attention. |
|
- You can set `low_rank_training` as `False` if you want to use fully fine-tuning. It will cost more GPU memory and slower, but the performance will be a bit better. |
|
- When training is finished, to get the full model weight: |
|
``` |
|
cd path_to_saving_checkpoints && python zero_to_fp32.py . pytorch_model.bin |
|
``` |
|
|
|
### Supervised Fine-tuning |
|
``` |
|
torchrun --nproc_per_node=8 supervised-fine-tune.py \ |
|
--model_name_or_path path_to_Llama2_chat_models \ |
|
--bf16 True \ |
|
--output_dir path_to_saving_checkpoints \ |
|
--model_max_length 32768 \ |
|
--use_flash_attn True \ |
|
--data_path LongAlpaca-12k.json \ |
|
--low_rank_training True \ |
|
--num_train_epochs 3 \ |
|
--per_device_train_batch_size 1 \ |
|
--per_device_eval_batch_size 2 \ |
|
--gradient_accumulation_steps 1 \ |
|
--evaluation_strategy "no" \ |
|
--save_strategy "steps" \ |
|
--save_steps 1000 \ |
|
--save_total_limit 2 \ |
|
--learning_rate 2e-5 \ |
|
--weight_decay 0.0 \ |
|
--warmup_steps 20 \ |
|
--lr_scheduler_type "constant_with_warmup" \ |
|
--logging_steps 1 \ |
|
--deepspeed "ds_configs/stage2.json" \ |
|
--tf32 True |
|
``` |
|
- There is no need to make supervised fine-tuning upon the fine-tuned context extended models. It is all right to directly use base model as Llama2-chat models, as the amount of long instruction following data is enough for SFT. |
|
- Our long instruction following data can be found in [LongAlpaca-12k.json](https://huggingface.co/datasets/Yukang/LongAlpaca-12k). |
|
|
|
|
|
### Get trainable weights in low-rank training |
|
In low-rank training, we set embedding and normalization layers as trainable. Please use the following line to extract the trainable weights `trainable_params.bin` from `pytorch_model.bin` |
|
``` |
|
python3 get_trainable_weights.py --checkpoint_path path_to_saving_checkpoints --trainable_params "embed,norm" |
|
``` |
|
|
|
### Merge LoRA Weight |
|
Merge the LoRA weights of `pytorch_model.bin` and trainable parameters `trainable_params.bin`, save the resulting model into your desired path in the Hugging Face format: |
|
``` |
|
python3 merge_lora_weights_and_save_hf_model.py \ |
|
--base_model path_to/Llama-2-7b-hf \ |
|
--peft_model path_to_saving_checkpoints \ |
|
--context_size 8192 \ |
|
--save_path path_to_saving_merged_model |
|
``` |
|
For example, |
|
``` |
|
python3 merge_lora_weights_and_save_hf_model.py \ |
|
--base_model /dataset/pretrained-models/Llama-2-7b-hf \ |
|
--peft_model /dataset/yukangchen/hf_models/lora-models/Llama-2-7b-longlora-8k \ |
|
--context_size 8192 \ |
|
--save_path /dataset/yukangchen/models/Llama-2-7b-longlora-8k-merged |
|
``` |
|
|
|
|
|
## Evaluation |
|
### Perplexity Validation |
|
To evaluate a model that is trained in the low-rank setting, please set both `base_model` and `peft_model`. `base_model` is the pre-trained weight. `peft_model` is the path to the saved checkpoint, which should contain `trainable_params.bin`, `adapter_model.bin` and `adapter_config.json`. For example, |
|
``` |
|
python3 eval.py --seq_len 8192 --context_size 8192 --batch_size 1 --base_model path_to/Llama-2-7b-hf --peft_model path_to_saving_checkpoints --data_path pg19/test.bin |
|
``` |
|
|
|
To evaluate a model that is fully fine-tuned, you only need to set `base_model` as the path to the saved checkpoint, which should contain `pytorch_model.bin` and `config.json`. `peft_model` should be ignored. |
|
``` |
|
python3 eval.py --seq_len 8192 --context_size 8192 --batch_size 1 --base_model path_to_saving_checkpoints --data_path pg19/test.bin |
|
``` |
|
|
|
- Note that `--seq_len` is to set the sequence length for evaluation. `--context_size` is to set the context length of the model during fine-tuning. `--seq_len` should not be larger than `--context_size`. |
|
|
|
- We have already tokenized the validation and test splits of PG19 and proof-pile dataset into `pg19/validation.bin`, `pg19/test.bin`, and `proof-pile/test_sampled_data.bin`, with the tokenizer of LLaMA. `proof-pile/test_sampled_data.bin` contains 128 documents that are randomly sampled from the total proof-pile test split. For each document, it has at least 32768 tokens. We also release the sampled ids in [proof-pile/test_sampled_ids.bin](https://drive.google.com/file/d/1cnzWODLRQYAd7HeugzLCIhaqzaLZv7J5/view?usp=share_link). You can download them from the links below. |

|
|
|
|
|
### Passkey Retrieval |
|
We provide a manner to test the passkey retrieval accuracy. For example, |
|
``` |
|
python3 passkey_retrivial.py \ |
|
--context_size 32768 \ |
|
--base_model path_to/Llama-2-7b-longlora-32k \ |
|
--max_tokens 32768 \ |
|
--interval 1000 |
|
``` |
|
- Note that the `context_size` is the context length during fine-tuning. |
|
- `max_tokens` is maximum length for the document in passkey retrieval evaluation. |
|
- `interval` is the interval during the document length increasing. It is a rough number because the document increases by sentences. |
|
|
|
## Demo |
|
### Local Inference |
|
To chat with [Llama-2-13b-chat-longlora-32k-sft](https://huggingface.co/Yukang/Llama-2-13b-chat-longlora-32k-sft) or [Llama-2-70b-chat-longlora-32k-sft](https://huggingface.co/Yukang/Llama-2-70b-chat-longlora-32k-sft), you need to run `merge_lora_weights_and_save_hf_model.py` first, and then: |
|
``` |
|
python3 inference.py \ |
|
--base_model path_to_model \ |
|
--question $question \ |
|
--context_size $context_length \ |
|
--max_gen_len $max_gen_len \ |
|
--flash_attn True \ |
|
--material $material_content \ |
|
--material_type $material_type \ |
|
--material_title $material_title |
|
``` |
|
To ask a question related to a book: |
|
``` |
|
python3 inference.py \ |
|
--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \ |
|
--question "Why doesn't Professor Snape seem to like Harry?" \ |
|
--context_size 32768 \ |
|
--max_gen_len 512 \ |
|
--flash_attn True \ |
|
--material "materials/Harry Potter and the Philosophers Stone_section2.txt" \ |
|
--material_type "book" \ |
|
--material_title "Harry Potter and the Philosophers Stone" |
|
``` |
|
Note that you can ignore `material_type` or `material_title`. |
|
|
|
To ask a question related to a paper: |
|
``` |
|
python3 inference.py \ |
|
--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \ |
|
--question "What are the main contributions and novelties of this work?" \ |
|
--context_size 32768 \ |
|
--max_gen_len 512 \ |
|
--flash_attn True \ |
|
--material "materials/paper1.txt" \ |
|
--material_type "paper" |
|
``` |
|
|
|
### Online Demo |
|
To deploy your own demo run |
|
``` |
|
python3 demo.py \ |
|
--base_model path_to_model \ |
|
--context_size $context_size \ |
|
--max_gen_len $max_gen_len \ |
|
--flash_attn True |
|
``` |
|
Example |
|
``` |
|
python3 demo.py \ |
|
--base_model /data/models/Llama-2-13b-chat-longlora-32k-sft \ |
|
--context_size 32768 \ |
|
--max_gen_len 512 \ |
|
--flash_attn True |
|
``` |
|
- Note that `flash_attn=True` will make the generation slow but save much GPU memory. |
|
|
|
## Data Generation via Pdf2text |
|
During our dataset collection, we convert paper and books from pdf to text. The conversion quality has a large influence on the final model quality. We think that this step is non-trivial. We release the tool for the pdf2txt conversion, in the folder `pdf2txt`. It is built upon `pdf2image`, `easyocr`, `ditod` and `detectron2`. Please refer to the [README.md](pdf2txt/README.md) in `pdf2txt` for more details. |
