I have successfully created a digraph of some sixty vertices. I am now trying to find shortest paths. I use the statement
*pa = ethics_net.get_shortest_paths(beg_node,end_node)* I am told by the system: *ValueError: no such vertex: '12'*. There is a vertex 12, I created it with this statement: * ethics_net = igraph.Graph(n =len(sorted_keys), directed = True)* Where have I gone wrong? As usual, thanks for your excellent help. Herb
