Initial setup on Mac M1

after running conda env create -f env.yml on my mac M1 in China it reports such an error:

I 'm not familiar with torch but I know it may has something to do with cuda. I tried removing two packages regarding cuda but it still reports the same error.
Anybody kindly offer guidance? I'm just trying to adopting it to my course project and the data prepared is small, unnecessary referring to GPU, I guess.

There are some known issues of using pytorch-geometric on Apple M1/2/3. For me, installing the latest pytorch-geometric's cpu version suffices to run this repo.

pip install torch_geometric pyg_lib torch_scatter torch_sparse torch_cluster torch_spline_conv -f https://data.pyg.org/whl/torch-2.3.0+cpu.html

Other libraries used by this repo can be pip installed. E.g., datatable, wandb. You may need to make wandb offline to run the codes due to connection stability in CN, btw.
