Error while using LinkLoaderNeighbor function which is indirectly due to installations issues. (Please consider it urgently as my project is stuck due this)

🐛 Describe the bug

I am attaching the Image of the bug:

Environment

• pyg-lib version:
• PyTorch version: 2.2.1+cu121
• OS: Windows
• Python version:3.10.12
• CUDA/cuDNN version: CPU
• How you installed PyTorch and pyg-lib (conda, pip, source): pip (Note: there was also issue which is currently already opened by someone regarding the setup.py file)
• Any other relevant information:

[rusty1s]

Have you considered to simply upgrade pyg-lib (as the error suggests)?

[ishanki19-pixel]

I am again and again getting error regarding the build failing, I have many different ways still build is getting failed for pyg-lib.

[ishanki19-pixel]

Actually, I have just gone through the repo of pyg-lib where I found that they have informed themselves that currently window wheels are not working and they are working over that!!! I hope this issue might get resolved asap!

[rusty1s]

I see. I missed the part that you are working on Windows. What does

pip install ninja wheel cmake
pip install --verbose git+https://github.com/pyg-team/pyg-lib.git

return in your case?

[ishanki19-pixel]

It returns the same error as told before! I hope the team would come up with a solution asap!

[rusty1s]

I was referring to the installation log, not the error you see when you wanna use edge-level temporal sampling.

[ishanki19-pixel]

Yeah, I was too referring to the installation itself! but there is problem with the wheels and setup.py file.

[rusty1s]

Can you post the installation log here when running

pip install ninja wheel cmake
pip uninstall pyg-lib
pip uninstall pyg-lib
pip install --verbose git+https://github.com/pyg-team/pyg-lib.git

[ishanki19-pixel]

After running the above code, I got this output:

[rusty1s]

Got it, can you try to install via

FORCE_CUDA=0 pip install --verbose git+https://github.com/pyg-team/pyg-lib.git

[ishanki19-pixel]

Getting the same errors:

[rusty1s]

That's very strange. It still tries to build CUDA although FORCE_CUDA=0 (seems Windows related). Can you download the repo locally, change this line to

            '-DWITH_CUDA=OFF',

and try again (by installing via pip install --verbose .)?

[ishanki19-pixel]

Its not working again, showing the same error even if I tried it running through my cmd.

[rusty1s]

Okay, I can try to find some time to enable Windows builds, but it may take some time. You can also try to install torch-sparse if pyg-lib causes issues.

[ishanki19-pixel]

Okay but pls try to fix this asap.

[rusty1s]

pyg-lib nows supports Windows, and you can install it from nightly:

pip install pyg-lib -f https://data.pyg.org/whl/nightly/torch-${TORCH}+${CUDA}.html

by replacing ${TORCH} and ${CUDA} according to your installation.

Thanks, @rusty1s, it works as it should be!

[ishanki19-pixel]
