- 2023/8/13: LLaMA2 7B + SFT+ RM + PPO + DeepSpeed training features finished
- 2023/07/30: OpenLLaMA2 project officially launched
OpenLLaMA2 aims to develop a high-performance distributed LLaMA2 SFT/RLHF training framework.
The sister project of this project is chinese-llama2 ↗, which aims to fine-tune the Chinese LLaMA2 using SFT/RLHF.
- [✔️] A fast LLaMA2 SFT/PPO Training Framework based on DeepSpeed.
- [✔️] Multi-nodes training scripts for Slurm.
- [✔️] Wandb log.
- [✔️] Support conda env.
- [✔️] FlashAttention2.
- [WIP] Multi-nodes RLHF based on Ray.
- [WIP] Multiple RM models.
- [WIP] Rejection Sampling.
- [WIP] Support QLora.
- [WIP] Support DPO.
- [WIP] Better docs and examples
- [WIP] Develop the RLHF datasets ↗ for Multiple reward models.
- [WIP] Train a chinese-llama2 ↗ RLHF model.
- [TODO] Support Context Distillation.
- [TODO] Inference kernel fusion (such as DS inference)
- [TODO] Large-scale model (> 70B) support with ZeRO++ and FasterTransformer inference.
- Verified envs
You can build openllama2 from nvidia-docker(recomended) or from conda envs.
Clone the repository:
git clone https://github.com/openllmai/OpenLLaMA2.git
# Download the pre-trained SFT/RM checkpoints (Optional)
git lfs install
git clone https://huggingface.co/chuyi777/openllama2_checkpoint- Single-node training with nvidia-docker
cd examples/scripts
# install nvidia-docker (Optional)
./nvidia_docker_install.sh
# launch nvidia container
./docker_run.sh
# cd in container
cd /openllama2/examples/scripts
# build OpenLLaMA2 (i.e, pip install)
./build_openllama2.sh
# huggingface login
~/.local/bin/huggingface-cli login
# train SFT model
./train_sft_llama.sh
# train RM model
./train_rm_llama.sh
# train PPO model
./train_ppo_llama.sh- Multi-nodes training on Slurm
cd examples/scripts
# huggingface login on Slurm
pip install transformers
huggingface-cli login
# Moidfy the Slurm Account/Nodes ... in `train_llama_slurm.sh`
# For SFT, RM, and PPO training stage:
# Modify the variable `training_script` in `train_llama_slurm.sh` to
readonly training_script="train_sft_llama.sh"
readonly training_script="train_rm_llama.sh"
readonly training_script="train_ppo_llama.sh"
# set `GPUS_PER_NODE` in `train_llama_slurm.sh`
readonly GPUS_PER_NODE=8
# run multi-nodes training script
# train_llama_slurm.sh will load the training args from `training_script`
sbatch ./train_llama_slurm.sh- build openllama2 from conda envs
If you really don't want to use nvidia-docker, we also provide tutorials for building openllama2 from a conda environment. (We prefer nvidia-docker to avoid errors caused by the environment.)
# we need conda
conda create -n llama2 python=3.10
# so, we need install some package manualy: when installing torch, you may need to match the corresponding cuda version.
pip install packaging ninja
pip install torch --index-url https://download.pytorch.org/whl/cu118
# check ninjia
ninja --version
echo $?
# install flash-attn: may take some time
pip install flash-attn=2.1.1 --no-build-isolation
./build_openllama2.sh
# enjoy it!After completing the training, you can evaluate your model by using the inference script:
./inference_llama.sh { model_path }If you want to contribute code please format the code using the following command,
pip install pre-commit
pre-commit install
git add .
git commit -m "xxx"
