• This issue is for the Python interface of igraph.
• This issue is a bug report or a feature request, not a support question.

The Python interface supports creating bipartite graphs from incidence matrices using Graph.Incidence. The corresponding function graph_from_incidence_matrix in the R library accepts an argument weighted (see documentation) to treat non-zero matrix values as edge weights, while the Python library does not.

It would be nice for python-igraph to have feature partity with R-igraph.
