I'm trying to retrieve all the nodes of a graph that belong to a specific
type. I use the find_vertex for this:
referents = find_vertex(graph, graph.vertex_properties['type'],
'referent')
But all I get is this error:
File "/usr/lib/python2.7/dist-packages/graph_tool/util/__init__.py",
line 58, in find_vertex
(val, val))
TypeError: No registered converter was able to extract a C++ reference to
type graph_tool::GraphInterface from this Python object of type
Graph.
Any clue of what is the problem?
