pyqt5-actions

Minimal working example of running .py file containing matplotlib.use('Qt5Agg') using python3-pyqt5.

import sys
import matplotlib
matplotlib.use('Qt5Agg')
from PyQt5.QtCore import QT_VERSION_STR
from PyQt5.Qt import PYQT_VERSION_STR
from sip import SIP_VERSION_STR

print(f'Python version: {sys.version}')
print(f'matplotlib version: {matplotlib.__version__}')
print(f'Qt version:{QT_VERSION_STR}')
print(f'SIP version:{SIP_VERSION_STR}')
print(f'PyQt version:{PYQT_VERSION_STR}')

What I learned

1. Curent version of matplotlib only support Python>=3.7.
2. It seems that python3-pyqt4 is no longer properly supported, thus python3-pyqt5 is recommended.
3. We can skip sudo apt-get install python3-pyqt5 and sololy rely on directly instally PyQt5 from pip.
