Pyqt5 autocomplete in PyCharm 2018, is it possible?

Question

Python

Good day.
Scripts run but autocomplete for PyQt5 in PyCharm doesn't work.
PyQt5 installed via PyCharm manager.
Error while importing module "Cannot find reference 'QtWidgets' in '__init__.py'".
All the solutions that I found in Google did not help and, as far as I understand, this bug has been dragging on almost since 2012.
