python - 如何在 Google Colab 上安装 nvidia apex

Question

我所做的是按照官方 github 站点上的说明进行操作

!git clone https://github.com/NVIDIA/apex
!cd apex
!pip install -v --no-cache-dir ./

它给了我错误:

ERROR: Directory './' is not installable. Neither 'setup.py' nor 'pyproject.toml' found.
Exception information:

(只想添加评论，但我没有足够的声誉......)

它对我有用，但 cd实际上不是必需的。另外，我需要这里建议的两个全局选项:https://github.com/NVIDIA/apex/issues/86

%%writefile setup.sh

git clone https://github.com/NVIDIA/apex
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./apex

那么

!sh setup.sh
