title: PyCall not working with a specific module
body: <p>I have been trying to call a specific python module ( <a href="https://github.com/wmayner/pyemd" rel="nofollow noreferrer">https://github.com/wmayner/pyemd</a> ) but I keep getting the followin error message:</p>
  
  <blockquote>
    <p>ERROR: PyError (:PyImport_ImportModule)

  <p>However, I am able to call python functions such as <em>"Hello world"</em> and I can use the module in a python environment. Do anyone knows a solution to this?</p>
