Installation instructions don't work

[jonas-eschle]

😵 Describe the installation problem

The instructions on how to install pyg with cuda support doesn't work (conda install pyg=*=*cu* -c pyg, taken from https://pytorch-geometric.readthedocs.io/en/latest/notes/installation.html). Tried in a fresh conda environment.

(Using the blocks conda, PyTorch 2.3, cuda 12.1 and linux)

Could not solve for environment specs
The following packages are incompatible
└─ pyg * *cu* is installable with the potential options
   ├─ pyg [2.0.0|2.0.1|2.0.2|2.0.3] would require
   │  └─ python >=3.6,<3.7.0a0 , which can be installed;

Environment

• OS: Ubuntu
• Python version: 3.11
• How you installed PyTorch and PyG (conda, pip, source): conda

Does conda install pyg -c pyg work for you?

[rusty1s]

And what happens if you run conda install pyg -c pyg -c nvidia -c pytorch?

yes, this does the trick! (without the additional channels, it won't work)

Hi, @jonas-eschle how did you make pyg work with PyTorch 2.3? It seems the published pyg package on anaconda does not support PyTorch 2.3 at all.

[jonas-eschle]

I simlpy used conda install pyg -c pyg -c nvidia -c pytorch (FYI, I also have conda-forge as a channel)

[chenzhekl]

Thanks! @jonas-eschle. Unfortunately, this command still does not work for me, where conda complained conflict packages. As a workaround, I installed pyg via PyPI in the end.

Actually this worked for me
