Newer version of pip will have issue during installation
Pip subprocess error:
WARNING: Ignoring version 1.8.1 of pytorch-lightning since it has invalid metadata:
Requested pytorch-lightning==1.8.1 from https://files.pythonhosted.org/packages/54/8f/ff9e74724d1c203e8f1efe4b763ef941as
torch (>=1.9.*)
~~~~~~^
Please use pip<24.1 if you need to use this version.
Try installing older version of pip to solve this problem. For instance,
pip install pip==23.
This is what works for me and it also works for GDR-Net and GDRNPP.
