# Shears Model Card: shears-mpt-7b-50-gsm8k-super

The super-adapter fine-tuned on sparsified MPT-7B with GSM8K datasets using Shears.

The release of the super-network is to facilitate users to apply their own search algorithms and evaluation indicators to extract subnetworks suitable for their specific needs.

## Model Details

### Information

- **Model name:** shears-mpt-7b-50-gsm8k-super
- **Base model:** [IntelLabs/MPT-7B-sparsity50](https://huggingface.co/IntelLabs/MPT-7B-sparsity50)
- **Sparsity:** 50%
- **Subnetwork version:** Super
- **NNCF Configuration:** [nncf_shears_mpt.json](https://github.com/IntelLabs/Hardware-Aware-Automated-Machine-Learning/tree/main/Shears/nncf_config/gsm8k/nncf_shears_mpt.json)

### Adapter Configuration

- **LoRA rank:** 32
- **LoRA alpha:** 64
- **LoRA target modules:** q_proj, k_proj, v_proj, out_proj, up_proj, down_proj
- **LoRA rank search space:** [32, 24, 16] (for each LoRA module)

### Training Hyperparameters

- **Batch size:** 16
- **Learning rate:** 3e-4
- **Epoch:** 5

### Training and Evaluation

GSM8K dataset: [https://huggingface.co/datasets/gsm8k](https://huggingface.co/datasets/gsm8k)

## How to use

Refer to the illustrative example provided in [load_and_explore_supernet.ipynb](https://github.com/IntelLabs/Hardware-Aware-Automated-Machine-Learning/tree/main/Shears/search/load_and_explore_supernet.ipynb) for a comprehensive understanding. This notebook shows the direct loading of a Shears super-network and the extraction of diverse subnetworks from it. 
This feature empowers users to employ their own search algorithms and evaluation metrics for the extraction of subnetworks customized to their specific requirements.

Moreover, the super-network is essentially the maximal subnetwork, and it can also be directly loaded:

```python
import torch
from peft import PeftModel
from transformers import AutoModelForCausalLM
from transformers import AutoTokenizer

def generate_prompt(instruction):
    return f"""Below is an instruction that describes a task. Write a response that appropriately completes the request. 

                    ### Instruction:
                    {instruction}

                    ### Response:
                    """

base_model = AutoModelForCausalLM.from_pretrained("IntelLabs/MPT-7B-sparsity50", trust_remote_code=True)
model = PeftModel.from_pretrained(base_model, "IntelLabs/shears-mpt-7b-50-gsm8k-super")
model.eval()

non_zero_params = sum([(param.data != 0).sum().item() for _, param in model.named_parameters()])
print(f"Number of all non-zero parameters: {non_zero_params}")

tokenizer = AutoTokenizer.from_pretrained("IntelLabs/MPT-7B-sparsity50", trust_remote_code=True)

instruction = "Edgar eats 18 pretzels a day. If his brother eats 1/2 as many, how many does his brother eat in a week?"
prompt = generate_prompt(instruction)
inputs = tokenizer(prompt, return_tensors="pt")
input_ids = inputs["input_ids"].to(model.device)
with torch.no_grad():
    generation_output = model.generate(
        input_ids=input_ids,
        return_dict_in_generate=True,
        output_scores=True,
        max_new_tokens=256,
        use_cache=True,
        num_beams=4,
    )
    s = generation_output.sequences[0]
    output = tokenizer.decode(s)
print(output)

```

## Evaluation Results
