How to forward important arguments to pip?

[npielawski]

Hello!

I am trying to use the library APEX, and I would like add --cuda_ext --cpp_ext to pip in order to install the library properly.

Is it possible to do this with pipenv? I already checked #251 and #287.

Have a nice day,
Nicolas

How do you pass that to pip? I don’t think you can just do pip install --cuda_ext 🤔

Technically, I'd like to do something along the lines:
pipenv install git+https://github.com/nvidia/apex.git --cuda_ext --cpp_ext
So that under the hood, the following command is called:
pip install . --cuda_ext --cpp_ext

You may be looking for the --global-option argument to pip. Per the documentation in the repository you linked, the actual pip install command would be:

$ pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" .

In order to achieve this with pipenv you simply need to set the environment variable PIP_GLOBAL_OPTION="--cpp_ext --cuda_ext" and it will be passed to pip (I think). Feel free to reopen this if it fails.
