title: Why can't I run python -m scripts.retrain -h from the Tensorflow for Poets example?
body: <p>I'm following the <em><a href="https://codelabs.developers.google.com/codelabs/tensorflow-for-poets/index.html#3" rel="nofollow noreferrer">Tensorflow for Poets</a></em> example to learn about image classification and I'm running into an error in the Terminal after running this command as instructed: </p>
  
  <pre><code>python -m scripts.retrain -h
  </code></pre>
  
  <p>The error I received is:</p>
  
  <pre><code>Traceback (most recent call last):
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/runpy.py", line 162, in _run_module_as_main

  </code></pre>
  
  <p>I ran pwd to confirm I was in the downloaded folder for the tutorial and it correctly shows:</p>
  
  <pre><code>/Users/qaneuro/poeticFlow/tensorflow-for-poets-2
  </code></pre>
  
  <p>Everything seemed to be working fine up until this point.  Any help or suggestions are greatly appreciated.</p>
