That's all ready simpler than that, as you can assign values of the propertymap like that: pm.a = a Le 20/03/2014 18:25, Pietro Battiston a écrit :

[...]I have now just added a Graph.add_edge_list() to the git version, which takes a list of edges to be added, which can be a numpy array. If you have a full adjacency matrix instead of an edge list, you can do simply:
g.add_edge_list(transpose(nonzero(a)))
This should be much faster than the Python loop above.
Do you think it would make sense then to have something analogous for PropertyMaps?
Like:
pm.set_from_list(a)
in place of:
for v in g.vertices(): pm[v] = a[i]
if pm is a property for vertices, and
for e in g.edges(): pm[e] = a[i]
if it is for edges?
