Networkx version #4
Description
When I use this，I found a issue,The netwokx version is not define and I try many times.Finally, It could run when networkx==1.9 and I change the code in 189th row.
189th row reachable_from_v1 = nx.connected.node_connected_component(self.G, edge[0])
I don't know if it's right?
If author or others see it ,I wish you can tell me is it right?
