Installation

siiRL provides three primary installation methods. We strongly recommend using the Docker image for the most reliable and hassle-free experience.

• Method 1: Install from Docker Image (Recommended)

• Method 2: Install from PyPI (pip)

• Method 3: Install from Source (Custom Environment)

Requirements

• Python: Version >= 3.10

• CUDA: Version >= 12.1

Currently, siiRL supports the following configurations are available:

• FSDP for training.

• SGLang and vLLM for rollout generation.

Method 1: Install from docker image

The stable image is siiai/siirl-base:vllm0.8.5.post1-sglang0.4.6.post5-cu124. This images contains the latest version of inference and training framework and its dependencies.

Method 2: Install from PIP

We provide prebuilt python wheels for Linux. Install siiRL with the following command:

# Install siiRL with vLLM
pip install siirl[vllm]

# Then, install required high-performance dependencies for siiRL
pip install flashinfer-python -i https://flashinfer.ai/whl/cu124/torch2.6/
pip install flash-attn==2.7.3 --no-build-isolation

Method 3: Install from custom environment

We recommend to use docker images for convenience. However, if your environment is not compatible with the docker image, you can also install siirl in a python environment.

Install dependencies

1. First of all, to manage environment, we recommend using conda:

conda create -n siirl python==3.10
conda activate siirl

2. Install python packages

Note

The following commands are an example for an environment with CUDA 12.4. If you are using a different CUDA version, you must adjust the package versions and index URLs accordingly, especially for torch, flashinfer, and flash-attn.

pip install torch==2.6.0 torchvision==0.21.0 torchaudio==2.6.0 --index-url https://download.pytorch.org/whl/cu124
pip install flashinfer-python -i https://flashinfer.ai/whl/cu124/torch2.6/
pip install flash-attn==2.7.3 --no-build-isolation
pip install accelerate codetiming datasets dill hydra-core pandas wandb loguru tensorboard qwen_vl_utils
pip install 'ray[default]>=2.47.1'
pip install opentelemetry-exporter-prometheus==0.47b0

3. Then, execute the following commands to install vLLM and SGLang:

pip install vllm==0.8.5.post1

Install siirl

For installing the latest version of siirl, the best way is to clone and install it from source. Then you can modify our code to customize your own post-training jobs.

git clone https://github.com/sii-research/siiRL.git
cd siirl
pip install -e .
