title: Problem in getting relative import in Python
body: <p>in my case I have folder structure as :</p>
  <pre><code>|- category 
  |  |- sub-category
  |    |- do_something.py
  |
  |- package
  |  | -module.py
  </code></pre>
  <p>I want to import function present in module.py inside do_something.py, something like :</p>
  <p><code>from ..package.module import func_1</code></p>
  <p>How should I do this , I have tried relative path but keep getting error like :</p>
  <p><code> ImportError: attempted relative import with no known parent package</code></p>
