title: Python 3.6.x PyInstaller gives error "No module named 'PyQt5.sip'"
body: <p>I developed a few programs that runs well on Python 3.5.4, but because of some errors about win32 made me go to Python 3.6.4, but when I build my project with pyinstaller, I get:</p>
  
  <pre><code>C:\Users\User\Desktop\dist\mycommentator&gt;mycommentator.exe
  Traceback (most recent call last):
    File "mycommentator.py", line 6, in &lt;module&gt;
    File "c:\users\user\appdata\local\programs\python\python36\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 714, in load_module
      module = loader.load_module(fullname)
  ModuleNotFoundError: No module named 'PyQt5.sip'
  [1532] Failed to execute script mycommentator
  </code></pre>
  
  <p>I tried to reinstall python, so I installed Python 3.6.4/Python 3.6.5, that error happened to me too.
  No matter what code in PyQt5 I build, every time this error.</p>
  
  <p>I also tried to move <code>sip.pyd</code> to the project folder, but error still happens.
  I also tried <code>pip install --upgrade sip</code>, that didn't help.
  I also tried to install the develop version of the pyinstaller, that didn't help too.</p>
