title: Installing prettytensor for TensorFlow not working on OSX
body: <p>I can't install <code>prettytensor</code>. I've tried doing it through <code>pip</code> and also by installing the sourcecode and doing <code>python setup.py install</code> in the directory. </p>
  
  <p><strong>I updated my <code>tensorflow</code> . Does anyone have any idea on how I can install <code>prettytensor</code> on my machine?</strong> </p>
  
  <pre><code>pip install prettytensor
