How to install packages using -f flag, such as when installing Pytorch?

[DanielPerezJensen]

I need to install a certain version of Pytorch that I can use with a certain version of Cuda. Normally when using pip I'd install it in the following way:

pip install torch==1.7.1+cu110 torchvision==0.8.2+cu110 torchaudio===0.7.2 -f https://download.pytorch.org/whl/torch_stable.html

But when I run that using pipenv, so in the following way:

pipenv install torch==1.7.1+cu110 torchvision==0.8.2+cu110 torchaudio===0.7.2 -f https://download.pytorch.org/whl/torch_stable.html

I get the following error:

Installing torch==1.7.1+cu110...
Error:  An error occurred while installing torch==1.7.1+cu110!
Error text: 
ERROR: Could not find a version that satisfies the requirement torch==1.7.1+cu110
ERROR: No matching distribution found for torch==1.7.1+cu110

What is the proper way to handle this using pipenv? Simply to install it using pip anyway, or something else?

These installations instructions come from the Pytorch getting started guide.

I have the same issue. Created this, but perhaps we can close one as a dupe?

Ah yes, I'll close this one and refer to yours.
