Re: [graph-tool] Nested Block State hierarchy level after mcmc_equilibrate

I just found out the following (using gt 2.29):

If I create a GraphView of g and store it in g,

g = gt.extract_largest_component(g)

infer an SBM,

state = gt.minimize_nested_blockmodel_dl(g)

and try to draw it,

state.draw()

then I get the "RuntimeError: Invalid hierarchical tree: No path from source to target."

But if I prune the graph,

g = gt.extract_largest_component(g, prune=True)

then everything's fine.

Hope this documentation is helpful.

There are many empty branches and when I try to plot it with empty_branches = False, I get an error stating it is not a tree. RuntimeError: Invalid hierarchical tree: No path from source to target.

Which version are you using?

Please provide a minimal and self-contained example that shows the problem.

Best, Tiago
