I don't know -- boost.graph experts have to say.

It looks like your graph doesn't have an edge property map :) I've never actually used the Python bindings, so this might not translate too well. You have to create your graphs with all of the properties that they're going to use later. My guess is that you're not explicitly creating an edge weight property with the graph, which would lead to this exception.

As a caveat... I don't know if the Python bindings are actively maintained - I'd guess no. It may be tough to get good answers to your questions.
