I run the following program (Python 3.6) listed here: http://zetcode.com/gui/pyqt5/firstprograms/

import sys
from PyQt5.QtWidgets import QApplication, QWidget`


if __name__ == '__main__':

    app = QApplication(sys.argv)

    w = QWidget()
    w.resize(250, 150)
    w.move(300, 300)
    w.setWindowTitle('Simple')
    w.show()

    sys.exit(app.exec_())

and continue to receive errors. I moved a few folders around after some other errors but things should be working now. I receive the following error:

from PyQt5.QtWidgets import QApplication, QWidget
SystemError: initialization of QtWidgets failed without raising an exception

What I have tried:

I installed QT but also installed PyQt5 and Sip Via Homebrew and Pip. Updated to the most recent versions of both, ran the -qmake and make install commands- took about 30 min. Typed this in the terminal (Mac):

python3 configure.py --qmake=/usr/local/Cellar/qt5/5.8.0_1/bin/qmake --sip=/usr/local/Cellar/sip/4.19.1/

Then make then make install.
No errors.

no errors when I

import PyQt5

I would really appreciate any help. Thank you.
