xformers v0.0.28版本Linux&Windows平台安装pip命令参考：
# [linux only] cuda 11.8 version
pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu118
# [linux only] cuda 12.1 version
pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu121
# [linux & win] cuda 12.4 version
pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu124
# [linux only] (EXPERIMENTAL) rocm 6.1 version
pip3 install -U xformers --index-url https://download.pytorch.org/whl/rocm6.1安装xformers的时候可以和torch一起安装，不然的话torch还会再重新安装一次，而且torch会自动选择到当前xformers支持到的最新版本，可能会与你当前想要的torch版本不一样导致torchvision等版本冲突。例如指定安装最新版torch 2.5.1和xformers 0.0.28.post3和cu124,可以使用如下安装命令：
pip install torch==2.5.1 torchvision==0.20.1 torchaudio==2.5.1 xformers==0.0.28.post3 --index-url https://download.pytorch.org/whl/cu124附：
