Conda stuck on Installing pip dependencies when trying to create env

When I try to run conda env create -f environment.yml, it gets stuck on Installing pip dependencies: /

Hi, thanks for the information. I believe the problem was that the pip packages of pytorch-geometric now are named with an underscore instead of a dash. Could you test if it works with the updated environment file from my last commit? The installation took about 10min on my PC, maybe let it run for some time.

If it still does not work please let me know as well!
Yours

Thanks for the response. I was able to create the conda env after changing torch_spline-conv to torch_spline_conv, but when I try to run mutag.py, I get

RuntimeError:
object has no attribute sparse_csc_tensor:

Searching around, this issue seems to be fixed by downgrading the version of torch sparse but I'm currently having issues doing that

Thanks for the remark! The new versions of pytorch geometric require a newer python version and have a different import path for GNNExplainer. I updated the environment file and the call to GNNExplainer. If you remove your old environment with
conda remove --name subgraphx --all
and then install the environment again, it should work. If it doesn't feel free to contact me again!
