LLaMA Efficient Tuning

Requirement

Python 3.8+ and PyTorch 1.13.1
🤗Transformers, Datasets, Accelerate, PEFT and TRL
protobuf, cpm_kernels and sentencepiece
jieba, rouge_chinese and nltk (used at evaluation)
gradio and mdtex2html (used in web_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 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

LLaMA Weights Preparation

Download the weights of the LLaMA models.
Convert them to HF format using this script

python convert_llama_weights_to_hf.py \
    --input_dir path_to_llama_weights --model_size 7B --output_dir path_to_llama_model
