'This error originates from a subprocess, and is likely not a problem with pip'

[gymoon10]

I tried to install apex with window and torch.version = 1.13.1+cu117. I followed the commands but it did not works.

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

The total error message shows as below. I'm sorry to bother you, but I'd appreciate your help. Thank you for your hard works.

This means that cuda_dir is not found. It is likely that you enables global option --cuda_ext but lack development environment of cuda. You may probably have installed cudatoolkit from conda/mamba/pip, which only provides CUDA runtime.
You can refer to the official guide to install nvcc which provides the cuda dev environment. Or simply use

conda install cudatoolkit-dev=<VERSION>

where <VERSION> ought to be same as the version of your cudatoolkit if you installed it. You may check if you have successfully installed nvcc by nvcc --version.
You can also omit the option --cuda_ext with the loss of some performance so that you do not need extra lib.

cuda 11.7
python3.7.6
torch==1.13.1
torchvision==0.14.1
torchaudio==0.13.1

unzip apex.zip
cd apex

1、install no cuda
python setup.py install

2、 install with cuda
python setup.py install --cuda_ext
The compilation process is very long, at least ten minutes, and the CPU and memory footprint is 8c 8G
