Problems with multiflip_mcmc_sweep

Hello,

I’m trying to use multiflip_mcmc_sweep to refine the inference of a nested block model. I am loading the state from a previous saved pickle. However, when I run the script, the function enters the loop a few times before the script crashes with the following error:

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

I’m using graph_tool version 2.96 and Python 3.10 within a conda environment.

A minimal working example and the full error output are available here:
:point_right: https://github.com/timeipert/graph_tool_test/tree/master

Could this be an issue with my usage, or might it indicate a bug in the function?

Thank you very much in advance for your help!

Best regards
