Bus error from running metis.part_graph in Python

I am on MacOS with M3 Max, Sonoma 14.6.1.

I installed following the instructions for GKlib and then METIS https://github.com/KarypisLab/GKlib https://github.com/KarypisLab/METIS

then I set the environment variables for METIS_DLL, METIS_IDXTYPEWIDTH, METIS_REALTYPEWIDTH manually in .zshrc

Then I do pip install metis

With python 3.9 and 3.12, I tried: `import metis import networkx as nx

G = nx.balanced_tree(3,3) (num_edgecuts, parts) = metis.part_graph(G, nparts=5)`

Which returns:

zsh: bus error python3

I've tried a bunch of different variations of setting METIS_IDXTYPEWIDTH, METIS_REALTYPEWIDTH in the metis files, but I cannot get around this bus error. Is anyone else seeing this behavior? Thanks!
