I have a graph composed by two different sets of edges. The first set is made by edges of weight 1 (list 1). The second set is made by edges of weight 2 (list 2). First, I create the graph with networkx and then use add_edges_from to add list 1 and list 2. I would like to compute all the shortest paths in this weighted graph. Basically I'm looking for the analogous of "all_shortest_paths" but with weights (looks like "dijkstra" module does not allow you to know all the possible routes between a given source and a given target). If I try to use "all_shortest_path" with weighted links (3-tuples, the two nodes and the weight) I get the error . Can anybody help me? Thanks a lot!
