STEP1
# 0 Download the source and create a Python 3.10.9 environment using conda or create a venv using python git clone https://github.com/deepbeepmeep/Wan2GP.git cd Wan2GP conda create -n wan2gp python=3.10.9 conda activate wan2gp

STEP2

原文是
# 1 Install pytorch 2.6.0 pip install torch==2.6.0 torchvision torchaudio --index-url https://download.pytorch.org/whl/test/cu124
但是我的cuda是12.8
只能使用如下命令
pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cu128

STEP4
`# 3.1 optional Sage attention support (30% faster, easy to install on Linux but much harder on Windows)
pip install sageattention==1.0.6

or for Sage Attention 2 (40% faster, sorry only manual compilation for the moment)

git clone https://github.com/thu-ml/SageAttention
cd SageAttention
pip install -e .`
我使用第二种安装

使用第二种方式安装失败，还是用第一种方式安装

STEP5
# 3.2 optional Flash attention support (easy to install on Linux but much harder on Windows) pip install flash-attn==2.7.2.post1
