LLM-Genie: an integrated framework for LLM training

Supported Models

Model	Model size	Default module	Template
LLaMA	7B/13B/33B/65B	q_proj,v_proj	-
LLaMA-2	7B/13B/70B	q_proj,v_proj	llama2
Falcon	7B/40B	query_key_value	-
Qwen	7B	c_attn	chatml

Default module is used for the --lora_target argument. Please use python src/train_bash.py -h to see all available options.
For the "base" models, the --template argument can be chosen from default, alpaca, vicuna etc. But make sure to use the corresponding template for the "chat" models.

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

Python 3.8+ and PyTorch 1.13.1+
🤗Transformers, Datasets, Accelerate, PEFT and TRL

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/byte-genie/llm-genie.git
conda create -n llm-genie python=3.10
conda activate llm-genie
cd llm-genie
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

    --deepspeed ds_config.json \
    ... # arguments (same as above)
