Issue
Should be an easy fix but apparently isn’t. I’m trying to run PyQt5 on my Ubuntu 18.04 machine. I have installed (or at least I think I have) Qt and PyQt5. I was even able to successfully execute pyuic5 main_window.ui -o MainWindow.py without any issues.
But when I run my code I get the following error:
Traceback (most recent call last):
File "MainWindow.py", line 79, in <module>
from qwt_text_label import QwtTextLabel
ModuleNotFoundError: No module named 'qwt_text_label'
What package am I missing? how do I install it? is it a linking error, or path variable? Any help would be appreciated.
Installation commands I have run:
python3.8 -m pip install pyqt5
sudo apt-get install qt5-default
Here is my main_window.ui:

from qwt_text_label import QwtTextLabel
Solution
Have you tried doing this?
from qwt.text import QwtTextLabel
requires python QWT.
