Changelog

[23/08/03] Now we support training the Qwen-7B model in this repo. Try --model_name_or_path Qwen/Qwen-7B-Chat and --lora_target c_attn arguments to train the Qwen-7B model. Remember to use --template chatml argument when you are using the Qwen-7B-Chat model.

[23/07/31] Now we support dataset streaming. Try --streaming and --max_steps 100 arguments to stream your dataset.

[23/07/29] We release two instruction-tuned 13B models at Hugging Face. See these Hugging Face Repos (LLaMA-2 / Baichuan) for details.

[23/07/19] Now we support training the LLaMA-2 models in this repo. Try --model_name_or_path meta-llama/Llama-2-7b-hf argument to use the LLaMA-2 model. Remember to use --template llama2 argument when you are using the LLaMA-2-chat model.

[23/07/18] Now we develop an all-in-one Web UI for training, evaluation and inference. Try train_web.py to fine-tune models in your Web browser. Thank @KanadeSiina and @codemayq for their efforts in the development.

[23/07/11] Now we support training the Baichuan-13B model in this repo. Try --model_name_or_path baichuan-inc/Baichuan-13B-Base and --lora_target W_pack arguments to train the Baichuan-13B model. Remember to use --template baichuan argument when you are using the Baichuan-13B-Chat model.

[23/06/29] We provide a reproducible example of training a chat model using instruction-following datasets, see this Hugging Face Repo for details.

[23/06/22] Now we align the demo API with the OpenAI's 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.

Supported Training Approaches

Provided Datasets

Please refer to data/README.md for details.

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

pip install --upgrade huggingface_hub
huggingface-cli login

Requirement

  • Python 3.8+ and PyTorch 1.13.1+
  • 🤗Transformers, Datasets, Accelerate, PEFT and TRL
  • sentencepiece and tiktoken
  • jieba, rouge-chinese and nltk (used at evaluation)
  • gradio and matplotlib (used in web_demo.py)
  • uvicorn, fastapi and sse-starlette (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 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.

Dependence Installation (optional)

git lfs install
git clone https://github.com/hiyouga/LLaMA-Efficient-Tuning.git
conda create -n llama_etuning python=3.10
conda activate llama_etuning
cd LLaMA-Efficient-Tuning
pip install -r requirements.txt

If you want to enable the quantized LoRA (QLoRA) on the Windows platform, you will be required to install a pre-built version of bitsandbytes library, which supports CUDA 11.1 to 12.1.

pip install https://github.com/jllllll/bitsandbytes-windows-webui/releases/download/wheels/bitsandbytes-0.39.1-py3-none-win_amd64.whl
