[FIXED] 'Graph' object has no attribute 'nodes_iter' in networkx module python

Issue

I have the below function in python2.7 using networkx module which produces the error.

for H in networkx.connected_component_subgraphs(G):
    bestScore = -1.0
    for n, d in H.nodes_iter(data=True):
        if d['Score'] > bestScore:
            bestScore = d['Score']
            bestSV = n
    if bestSV is not None:
        selectedSVs.add(bestSV)

Error:

Traceback (most recent call last):
File "cnvClassifier.py", line 128, in <module>
for n, d in H.nodes_iter(data=True):
AttributeError: 'Graph' object has no attribute 'nodes_iter'

Does anybody have any idea what has been wrong?

Solution

You are probably using the pre-release version of networkx-2.0 which has removed the nodes_iter() method and now provides the the nodes() method with the same functionality. See this for details on the networkx-2.0 changes.
