This might be a stupid question, but I have a graph with a vector<str>-valued vertex property map. That is, each vertex has a vector containing one or more strings encoding some metadata about the vertex. I want to get a single 1d-list/array containing all the unique string values encoded in this property map, over all vertices in the graph. What's the best way to do that? I know that I'll have to use the get_2d_array() method on the property map, but I can't really understand what the documentation means when it says: "The parameter pos must be a sequence of integers which specifies the *indexes of the property values which will be used.*" -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
