[23/09/10] Now we support using FlashAttention for the LLaMA models. Try --flash_attn
argument to enable FlashAttention-2 if you are using RTX4090, A100 or H100 GPUs (experimental feature).
[23/08/18] Now we support resuming training, upgrade transformers
to 4.31.0
to enjoy this feature.
[23/08/12] Now we support RoPE scaling to extend the context length of the LLaMA models. Try --rope_scaling linear
argument in training and --rope_scaling dynamic
argument at inference to extrapolate the position embeddings.
[23/08/11] Now we support DPO training for instruction-tuned models. See this example to train your models.
[23/07/31] Now we support dataset streaming. Try --streaming
and --max_steps 10000
arguments to load your dataset in streaming mode.
[23/07/29] We release two instruction-tuned 13B models at Hugging Face. See these Hugging Face Repos (LLaMA-2 / Baichuan) for details.
[23/07/18] 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.
[23/07/09] Now we release FastEdit ⚡🩹, an easy-to-use package for editing the factual knowledge of large language models efficiently. Please follow FastEdit if you are interested.
[23/06/29] We provide a reproducible example of training a chat model using instruction-following datasets, see Baichuan-7B-sft 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.
[23/06/03] Now we support quantized training and inference (aka QLoRA). Try --quantization_bit 4/8
argument to work with quantized 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 |
BLOOM | 560M/1.1B/1.7B/3B/7.1B/176B | query_key_value | - |

Falcon | 7B/40B | query_key_value | - |
Baichuan | 7B/13B | W_pack | baichuan |
Baichuan2 | 7B/13B | W_pack | baichuan2 |
InternLM | 7B | q_proj,v_proj | intern |
Qwen | 7B | c_attn | chatml |
XVERSE | 13B | q_proj,v_proj | xverse |
ChatGLM2 | 6B | query_key_value | chatglm2 |
Note
Default module is used for the --lora_target
argument, you can use --lora_target all
to specify all the available modules.
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.

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
.
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
CUDA_VISIBLE_DEVICES=0 python src/train_web.py
We strongly recommend using the all-in-one Web UI for newcomers since it can also generate training scripts automatically.
Warning
Currently the web UI only supports training on a single GPU.
Important
If you want to train models on multiple GPUs, please refer to Distributed Training.
