Note that the present implementation of the leading eigenvector method
does not support edge weights (it considers all weights being equal), so
you might be better of with a different community detection method that
can handle weights. E.g., Graph.community_fastgreedy() or
Graph.community_walktrap() supports weights if you specify the
weights=... keyword argument.
