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().
