`graphblas` a problem for Py312 on `osx-arm64`?

[jGaboardi]

Seems like graphblas might be a problem for Py312 on osx-arm64?

I didn't realise that my env with graphblas is running 3.11.8. Let's re-pin Python to 3.11.

[jGaboardi]

Is graphblas only needed for the clustering stuff though? If the clustering stuff is a deadend, shall we simply drop graphblas?

[martinfleis]

I was using it to clip the networks. I would surely keep it as if we'll need some graph-informed simplification stuff, I'd like to channel it via graphblas if possible for performance reasons.
