title: ImportError: cannot import name mpl (from matplotlib import mpl)
body: <p>I am trying to run a code that I wrote a couple of years ago that uses <code>mpl</code> from <code>matplotlib</code>. It used to run fine, but now suddently it's throwing an error:</p>
  
  <pre><code>from matplotlib import mpl
  ImportError: cannot import name mpl
  </code></pre>
  
  <p>I am using Python 2.7 and matplotlib 1.5.2.</p>
