安装Open-Sora需要分步骤完成环境配置：
- Creating a Python Virtual Environment：推荐使用Python 3.10版本，通过conda创建独立环境避免依赖冲突
conda create -n opensora python=3.10 conda activate opensora
- Cloning Codebase：从GitHub获取项目源码
git clone https://github.com/hpcaitech/Open-Sora cd Open-Sora
- Installing core dependencies：需确保PyTorch版本≥2.4.0
pip install -v .
开发模式下建议使用：
pip install -v -e .
- 加速库安装：根据CUDA版本安装性能优化库
pip install xformers==0.0.27.post2 --index-url ... pip install flash-attn --no-build-isolation
- Model Download：从Hugging Face或ModelScope获取预训练权重
huggingface-cli download hpcai-tech/Open-Sora-v2 --local-dir ./ckpts
安装完成后可通过python -c "import opensora; print(opensora.__version__)"Verify that it was successful.
