Function snap.GetBetweennessCentr(self.G, nodesKeyCentrVals, edgesKeyCentrVals, 1.0, boolean) should have been filled with boolean value (True), by default its False. On the documentation, its stated that True means direct
ed graph, and False means undirected graph. In the source code, stated that the node has source and dest node (which means that its a directed graph).
So my solution for this case is:
On Centrality.py (function genGraphInfoBetweeness())
Change:
snap.GetBetweennessCentr(self.G, nodesKeyCentrVals, edgesKeyCentrVals, 1.0)

To:
snap.GetBetweennessCentr(self.G, nodesKeyCentrVals, edgesKeyCentrVals, 1.0, True)
