title: Import a module from a sub package not working
body: <p>My file structure is</p>
  
  <pre><code>project/
      __init__.py
      features/
          __init__.py
          CompareText.py
      tests/
          test.py
  </code></pre>
  
  <p>in test.py I am trying to import CompareText</p>
  
  <pre class="lang-py prettyprint-override"><code>from project.features import CompareText
  </code></pre>
  
  <p>I get an error of:</p>
  
  <blockquote>
  <pre><code>ModuleNotFoundError: No module named 'features'`
  </code></pre>
  </blockquote>
  
  <p>I checked the documentation and I think my import statement is correct. How can I fix it?</p>
