title: import package which is installed in development mode
body: <p>I've cloned a github repository in the same directory as my project. Then I installed the module using <code>python3.6 setup.py develop</code>, because I need to debug the library.  </p>
  
  <p>Let's say the package is called <code>bar</code>. When I am trying to import the package with <code>import bar</code> it still uses the already installed package and not the development version.</p>
  
  <p>How can I specifically import the development package?</p>
