title: Unable to import class
body: <pre class="lang-none prettyprint-override"><code>Unit_Test/
      __init__.py
  widgets/
      __init__.py
  </code></pre>
  
  <p>In <code>Unit_Test/__init__.py</code>:</p>
  
  <pre><code>from .. widgets import PathPicker
  </code></pre>
  
  <p>I get the following error: <code>ValueError: Attempted relative import in non-package</code></p>
  
  <p><code>widgets/__init__.py</code> has a class named <code>PathPicker</code>.</p>
  
  <p><strong>Edit:</strong> In regards to the comment below, I am running the script from pyCharm. I opened the project from the folder 'lib' in this directory: <code>lib\pt_hil\utilities\PT_HIL_Interface_Utils\widgets</code></p>
