title: ImportError only when I use docker
body: <p>I can run a script fine without docker, but when I have to use docker I run it and I get an import error: no module named c.H.</p>
  
  <p>In my docker container, I can do: </p>
  
  <p>python</p>
  
  <pre><code> import c.H
  </code></pre>
  
  <p>Everything works fine. But the second I try to run script.py, I get the import error that there is no module named c.H</p>
  
  <p>I do not get this error when I don't use docker.</p>
