The Python "ModuleNotFoundError: No module named 'PyQt5'" occurs when we forget to install the PyQt5 module before importing it or install it in an incorrect environment. To solve the error, install the module by running the pip install PyQt5 command.
Enter the mainloop of application by app.Import QtCore, QtGui and QtWidgets modules from PyQt5 package. Create an application object of QApplication class. Add a QLabel object and set the caption of label as "hello world". Define the size and position of window by setGeometry() method.
To install PyQt on Windows there are a few steps you need to take. First use the installer from the qt-project website, from qt to install PyQt. Next you want to install a Python version 3.3 or newer. Check the box to add all of the PyQt5 extras.
If you are on ubuntu, just install pyqt5 with apt-get command:
sudo apt-get install python3-pyqt5 # for python3 or
sudo apt-get install python-pyqt5 # for python2 However, on Ubuntu 14.04 the python-pyqt5 package is left out [source] and need to be installed manually [source]

pip install pyqt5 for python3 for ubuntu
