Hi all. I'm trying to use the dijktstra search But I have a exception.The property that is used a int32_t and the GraphViews aren't empty. Any clue of what is my error? This is the code: referents_graph = GraphView(graph, vfilt= lambda v: graph.vertex_properties["type"][v]=="referent") navigable_graph = GraphView(graph, reversed=True) referents = referents_graph.vertices() weight = navigable_graph.edge_properties["weight"] for base_referent in referents: # Calculate the distance of all accessible referents distances, predecessors = graph_tool.search.dijkstra_search(navigable_graph,base_referent,weight) This is the trace: File "/data/workspace/stanford-corenlp-python/contextgenerator.py", line 218, in resolve_corefenrence distances, predecessors = graph_tool.search.dijkstra_search(navigable_graph,base_referent,weight) File "/usr/local/lib/python2.7/dist-packages/graph_tool/decorators.pyc", line 2, in dijkstra_search Bq�Oc File "/usr/local/lib/python2.7/dist-packages/graph_tool/search/__init__.py", line 126, in wrap ret = func(*args, **kwargs) File "/usr/local/lib/python2.7/dist-packages/graph_tool/search/__init__.py", line 841, in dijkstra_search compare, combine, zero, infinity) TypeError: No registered converter was able to produce a C++ rvalue of type int from this Python object of type float Thanks for the time. -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
