Description
OS: Windows 10
Python: 3.8.5
On a fresh virtual environment, i installed matplotlib version 3.4.1. When I import using
import matplotlib.pyplot as plt
It throws
AttributeError: module 'sip' has no attribute 'setapi'
With a bit of search, I see it is because of pyqt5.
Simply installing pyqt5 latest version 5.15.4 using
pip install PyQt5 resolve the error.
If matplotlib is using pyqt5, I believe it should be installed while installing matlotlib. Currently installing matplotlib is not installing pyqt. It install these packages numpy, six, python-dateutil, cycler, kiwisolver, pillow, pyparsing, matplotlib
