title: pySerial AttributeError: module 'serial' has no attribute 'Serial'
body: <p>I have windows 7 64 bit and Python 3.6 </p>
  
  <p>I literally dig entire web for solving this - and nothing works sadly.</p>
  
  <pre><code>AttributeError                            Traceback (most recent call last)
  &lt;ipython-input-150-80ee8bd5f0f2&gt; in &lt;module&gt;()
  ----&gt; serial.Serial()
  
  AttributeError: module 'serial' has no attribute 'Serial'
  </code></pre>
  
  <p>I tried solve this by:
  - checking if my file is named serial.py 
  - reinstalling module - at first, entire module didn't work, now only it's functions.
  - I can't use any of its features, checking ports don't work, nothing works literally.
  - I checked my pip - everything is fine, module is in folder site-pacages.
  - If I execute some code inside pySerial files - it works. But there is no serial.Serial or connecting with COM ports (which I try to do.)</p>
