title: FatalError failed to execute script. PyQt5
body: <p>I know that questions have already been raised on this topic, but I believe that all decisions were strictly individual. The essence of the problem:
  There is a calculator.py script and a kalkulator.py These files are in the same directory, the calculator file is executable, this is the file that I convert into an EXE using PyInstaller. Inside the file, I import several PyQt5 libraries, and the second file is Python: <strong>from kalkulator import *</strong>
  The second file kalkulator.py contains the GUI of the program created with QtDesigner</p>
  
  <p>When i run the command <strong>pyinstaller --onefile --debug calculator.py</strong> everything goes fine.</p>
  
  <p>But when I run the EXE program file in debug mode, I see the following error:</p>

  <p>The photo shows that the following error occurs.
  "DLL Load Failed: The specified procedure could not be found."</p>
  
  <p>I can assume that the problem is that when assembling, PyInstaller does not see the file kalkulator.py it contains a graphical interface.</p>
  
  <p>What can you say about this problem, how do you think you can solve it?</p>
  
  <p>I use:
  Python 3.5
  PyQt5
  PyInstaller 3.3.1</p>
