I want to use %matplotlib qt in jupyter notebook. I tried import PyQt5 and it worked. But when i run %matplotlib qt i got this errorImportError: Failed to import any qt bindingIssue is that my system is unable to import following packages.

from .backend_qt5 import ( QtCore, QtGui, QtWidgets, _BackendQT5, FigureCanvasQT, FigureManagerQT, NavigationToolbar2QT, backend_version)

I even installed QTCreator.

I am using Ubuntu version 20.04, Python 3.8
