Dear Tiago,
I upgraded to the version 2.24 (commit 9642dd05, Sat Oct 7 23:40:03 2017
+0100) and tried calculating gt.assortativity and gt.scalar_assortativity
by making a property map's values same for all nodes.
In [1]: import graph_tool.all as gt
In [2]: gt.__version__
Out[2]: '2.24 (commit 9642dd05, Sat Oct 7 23:40:03 2017 +0100)'
In [3]: g = gt.collection.data['karate']
In [4]: s = g.new_vertex_property('float')
In [5]: for v in g.vertices():
...: s[v] = 0.9999
In [6]: gt.scalar_assortativity(g, deg = s)
Out[6]: (1.0, 8.889098493616578)
In [7]: gt.assortativity(g, deg = s)
Out[7]: (nan, nan)
Shouldn't gt.scalar_assortativity also return (nan, nan) here?
Thank you
Snehal
