I get the following error
ImportError: cannot import name 'QtCore' from 'PyQt5' (/usr/lib/python3/dist-packages/PyQt5/init.py)
which makes me think that the module is not installed.
When I try to install it I get:
pip3 install PyQt5
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: PyQt5 in /usr/lib/python3/dist-packages (5.14.1)
I also tried the following and got
sudo pip3 install PyQt5
Requirement already satisfied: PyQt5 in /usr/lib/python3/dist-packages (5.14.1)

Any idea? I am running python3.10 on Ubuntu
CodePudding user response：
did you try to launch your program with python3 program.py or python program.py depending on the one you already use ?
Also try to run a pip3 list to see if the module is installed.
You can try to install with python3 -m pip install PyQT5 or just python -m pip install PyQT5
CodePudding user response：
you can try reinstalling
$ python3 -m pip install --upgrade --force-reinstall PyQt5
however I recommend using a virtual environment (e.g. using venv module) to install the modules and use them:
$ sudo apt install python3-venv
$ python3 -m venv my-project-env
$ source my-project-env/bin/activate
then install required modules in your project's virtual environment

It seems that you need to install/upgrade matplotlib.
