## Changelog

[23/06/22] Now we align the [demo API](src/api_demo.py) with the [OpenAI's](https://platform.openai.com/docs/api-reference/chat) format where you can insert the fine-tuned model in arbitrary ChatGPT-based applications.

[23/06/15] Now we support training the baichuan-7B model in this repo. Try `--model_name_or_path baichuan-inc/baichuan-7B` and `--lora_target W_pack` arguments to use the baichuan-7B model. If you want to train with RTX3090, use `git checkout baichuan-7b-rtx3090` to switch to the `baichuan-7b-rtx3090` branch and try the `--baichuan_rtx_gpu true` argument. (Other RTX series GPUs can also be tried)

[23/06/03] Now we support quantized training and inference (aka [QLoRA](https://github.com/artidoro/qlora)). Try `--quantization_bit 4/8` argument to work with quantized model. (experimental feature)

[23/05/31] Now we support training the BLOOM & BLOOMZ models in this repo. Try `--model_name_or_path bigscience/bloomz-7b1-mt` and `--lora_target query_key_value` arguments to use the BLOOMZ model.

Some datasets require confirmation before using them, so we recommend logging in with your HuggingFace account using these commands.

```bash
pip install --upgrade huggingface_hub
huggingface-cli login
```

## Requirement

- Python 3.8+ and PyTorch 1.13.1+
- 🤗Transformers, Datasets, Accelerate, PEFT and TRL
- jieba, rouge_chinese and nltk (used at evaluation)
- gradio and mdtex2html (used in web_demo.py)
- uvicorn and fastapi (used in api_demo.py)

And **powerful GPUs**!

## Getting Started

### Data Preparation (optional)

Please refer to `data/example_dataset` for checking the details about the format of dataset files. You can either use a single `.json` file or a [dataset loading script](https://huggingface.co/docs/datasets/dataset_script) with multiple files to create a custom dataset.

Note: please update `data/dataset_info.json` to use your custom dataset. About the format of this file, please refer to `data/README.md`.
