I read this page and followed Anže Starič's opinion.
My computer is
- Windows 10
- Python 3.5
- PyQt5
- PyCharm 5.0.1
So I typed:
python "C:\Program Files\JetBrains\PyCharm 5.0.1\helpers\generator3.py" -x -d "C:\Users\user\.PyCharm50\system\python_stubs\324234324" PyQt5
python "C:\Program Files\JetBrains\PyCharm 5.0.1\helpers\generator3.py" -x -d "C:\Users\user\.PyCharm50\system\python_stubs\324234324" PyQt5.QtCore
python "C:\Program Files\JetBrains\PyCharm 5.0.1\helpers\generator3.py" -x -d "C:\Users\user\.PyCharm50\system\python_stubs\324234324" PyQt5.QtWidgets
......
I tried EVERY module. Of course, you can write a batch file/shell script and you should change those paths to your own.
Finally the autocomplete works.
