Install torch==1.8.2+cpu, torch==1.8.2+cu102 with "-f https://download.pytorch.org/whl/lts/1.8/torch_lts.html"

[paantya]

pip3 install torch==1.8.2+cpu torchvision==0.9.2+cpu torchaudio==0.8.2 -f https://download.pytorch.org/whl/lts/1.8/torch_lts.html

I can not prescribe, so that it does not swear

1. torch==1.8.2+cpu, swears at +cpu
2. swears at -f https://download.pytorch.org/whl/lts/1.8/torch_lts.html

Can you please tell me how to write the installation of the following library in the file requirements.txt?

with pages: https://pytorch.org/get-started/locally/

pip3 install torch==1.8.2+cpu torchvision==0.9.2+cpu torchaudio==0.8.2 -f https://download.pytorch.org/whl/lts/1.8/torch_lts.html

or

pip3 install torch==1.8.2+cu102 torchvision==0.9.2+cu102 torchaudio==0.8.2 -f https://download.pytorch.org/whl/lts/1.8/torch_lts.html
