body: <p>Using Windows 10 with Spyder IDE running Python 3.5. I am seeing following in the <code>__init__.py</code> file complaining about <code>unable to detect undefined names</code>:</p>

  <p>However, it seems <code>__init__.py</code> file is in the same folders as all other files. </p>

  <p>So why it is complaining? I tried to remove the leading dot in the front, but it still complains. Please give me some pointers.</p>
