Hi, I agree that the documentation in this case is not easy to understand. I had a similar situation and get_2d_array([0]) worked. Best, Alex On Fri, Feb 10, 2017 at 11:26 AM, gogurt <gogurt@gmail.com> wrote:
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.*"
