Hi,Guten Tag!
I am making the following example http://projects.skewed.de/graph-tool/wiki/FrontpageExample .
What I want to do is to extract the coordinates of the nodes into a list from the vertex property map (i.e. from the variable pos, I assume they are stored there). How do I do that? Please help me, because I am stuck on this problem for 2 days and I can't find the solution.
Best regards,Kiril

In this case, if I recall well, the
propery map pos
has elements of type vector<double>,
so you can't access to the data through the pos.a
attribute.
A simple loop will do though
pos_list = np.array([pos[v].a for v in g.vertices()])
