title: Read The Docs don't show any functions when using automodule
body: <p>I’ve got a problem visualizing the documentation of my project in Read the Docs. Everything works fine locally by executing the command <code>make html</code>, but in Read the Docs the functions that should be generated by the directive automodule don’t show up.</p>
  
  <p><a href="https://i.stack.imgur.com/kvmEM.png" rel="nofollow noreferrer">This</a> is how my repository is structured.  </p>
  
  <p>In the <strong>conf.py</strong> I set the absolute path as follows: <code>sys.path.insert(0, os.path.abspath('../..'))</code>, and then I used the following instruction for automatically describing the functions contained in the Python module in my documentation:  </p>
  
  <pre><code>.. automodule:: library.module1
      :members:
  </code></pre>
  
  <p>However, no functions are shown by compiling the doc in Read The Docs. 
  I also tried to install my project in a <em>virtualenv</em> by specifying a <strong>requirements.txt</strong> file in the RTD advanced settings, but this doesn’t work either. Any suggestions? </p>
