Hi all,

I'm trying to story vertex positions in a property map. Why doesn't it work the way I try?

from graph_tool.all import * import numpy as np g = Graph() pos = g.new_vertex_property('object') for i in range(1, 3):     v = g.add_vertex()     pos[v] = np.array([i, i]) graph_draw(g, pos=pos)

The position property map should be:

pos = g.new_vp("vector<double>")

Best, Tiago
