title: anaconda - graphviz - can't import after installation
body: <p>Just installed a package through anaconda (<code>conda install graphviz</code>), but ipython wouldn't find it.</p>
  
  <p>I can see a graphviz folder in <code>C:\Users\username\Anaconda\pkgs</code></p>
  
  <p>But there's nothing in: <code>C:\Users\username\Anaconda\Lib\site-packages</code></p>
