title: AttributeError: module 'networkx' has no attribute 'Graph'
body: <p>I installed networkx by downloading the distribution file and running:</p>
  <pre><code>python setup.py install
  </code></pre>
  <p>It appears to have been successful, I got this message after installing</p>
  <pre><code>Installed c:\python\python36-32\lib\site-packages\decorator-4.0.11-py3.6.egg
  Finished processing dependencies for networkx==1.11
  </code></pre>
  <p>But when I run a really simple test code, I get errors</p>
  <pre><code>import networkx as nx
  
  G=nx.Graph()
  
  print(G.nodes())
  print(G.edges())
  
  print(type(G.nodes()))
  print(type(G.edges()))
  </code></pre>
