For me it works fine in the IPython shell - only in the notebook it crashes. Well, case closed then, it’s probably not a NetworKit issue. Thanks.

Whats the output of D.toString() once the graph is read? Maybe something in your environment (python version, gcc) changed? Did you try rebuilding networkit completely?
