Unable to install torch==1.7.1

[op1009]

when doing pip install -r requirements.txt Error => Could not find a version that satisfies the requirement torch==1.7.1

After giving custom link from pytorch website pip install torch==1.7.1+cu92 torchvision==0.8.2+cu92 torchaudio==0.7.2 -f https://download.pytorch.org/whl/torch_stable.html also it gives error as:

after modifying torch==1.7.1 to torch in requirements.txt and re-installing everything it gives another error

Please suggest solutions @ArminMasoumian

The download links for PyTorch version 1.7.1 tailored to your CUDA model can be accessed at https://pytorch.org/get-started/previous-versions/#v171.

Thanks for reply.
The solution you are suggesting, I have already tried that(mentioned in first bold line in my description above). But still error is coming ERROR: Could not find a version that satisfies the requirement torch==1.7.1+cu92.

I'm uncertain about the specific issue, but there could be two potential reasons. First, ensure your Python version matches the required version. Second, check your proxy connection. Please visit this link to see if it provides a solution: Stack Overflow link.
