Dear all, after trying for a few days to resolve this myself, I decided to ask for help here.
The cookbook example on model evidence for the nested example fails on all my graphs, but works with the original gt.collection.data["lesmis"] graph. The code is exactly as in the cookbook example <https://graph-tool.skewed.de/static/doc/demos/inference/inference.html#model-class-selection> . The unnested SBM does work with every graph I tried. Here's the error message, which is triggered in the call to mcmc_equilibrate(). --- ArgumentError Traceback (most recent call last) <ipython-input-65-403d439ad6c7> in <module>() 32 # Now we collect
