Yes, will land (hopefully) early next week.

Sorry for late reply. This looks indeed wrong. Can you share your inputs that make it crash? Also @kgajdamo for visibility.

Can you try to fix the versioning according to the latest supported version of `torch-cluster` for PyTorch 1.8 (see [here](https://data.pyg.org/whl/torch-1.8.1+cu102.html))? ``` pip install torch-cluster==1.5.9 -f https://data.pyg.org/whl/torch-1.8.1+cu102.html ```

This error suggests that it is not actually picking up the wheels from https://data.pyg.org/whl/torch-1.8.1+cpu.html. Does `pipenv` support the `-f` option? What's the output when installing via `--verbose`?

I tested this here and it runs fine for us: https://github.com/pyg-team/pytorch_geometric/pull/9607. Not sure what causes this on your end.

You can send a PR with your initial implementation. I can try to optimize it in a follow-up.

Looking into this.

This should already work.
