pipenv option to mimic pip -f option

Question

In pip there is an -f option which does the following:

-f, --find-links : If a url or path to an html file, then parse for links to archives. If a local path or file:// url that's a directory, then look for archives in the directory listing.

This is the preferred way of installing PyTorch, by setting the link to their overview website, e.g.:

pip3 install torch===1.3.0 -f https://download.pytorch.org/whl/torch_stable.html

For my virtual environments I use pipenv but I haven't found an option that does the same as -f. In the meantime, I can just look up the direct link to the package that is relevant for my system, but that is cumbersome.

Does pipenv provide a way to do the same thing as pip's -f?

Answer 1

It is possible to use environment variables recognised by pip to tweak its behaviour within pipenv's execution. E.g.:

PIP_FIND_LINKS=https://download.pytorch.org/whl/torch_stable.html pipenv install torch==1.5.1+cu101

See:

• Advanced Usage of Pipenv - Configuration With Environment Variables
• pip's User Guide - Environment Variables

Answer 2

In the new version of pipenv (I tested with version 2020.11.15), you can install packages in this way:

pipenv install https://download.pytorch.org/whl/cpu/torch-1.3.0%2Bcpu-cp36-cp36m-linux_x86_64.whl

The link can be found in the this page: https://download.pytorch.org/whl/torch_stable.html

This will be added to the Pipfile as well.

[packages]
torch = {file = "https://download.pytorch.org/whl/cpu/torch-1.3.0%2Bcpu-cp36-cp36m-linux_x86_64.whl"}

you need to manually check the link with your compute platform, os and python version.
