title: Error importing with unittest and Python 3.6
body: <p>I am developing a small project using Python 3.6 version. Implementing the unit test with unittest I have an error executing <code>python3 -m unittest</code> and I have not an error executing <code>python -m unittest</code>.</p>
  
  <p>The error shows import error like:</p>
  
  <pre><code>ModuleNotFoundError: No module named 'genome'
  </code></pre>
  
  <p>Is there any import problem using unittest in Python 3.6?</p>
