title: While importing pyplot from matplotlib it hangs
body: <p>I am trying to import pyplot but my python code will not run and gets stuck at the following spot:</p>
  
  <p><code>from matplotlib import pyplot as plt</code></p>
  
  <pre><code>Traceback (most recent call last):

  <p>I have tried uninstalling matplotlib using pip so that I can reinstall the package but that also throws a lengthy list of errors.  I am running this on my Mac OSX 10.11.</p>
