Matplotlib in QML application

Witc

Hi, I wanted to plot data with matplotlib in my QML app. I found this example
But first error:

I installed the module several times. Is there any special on this module how to install it?

Thank you.

Hi,

Did you install that package ?

Witc

sure I installed it.. and uninstalled and again installed...

SGaist

How did you do that ?
Are you using a virtual environment ?
If so, which one ?

Witc

I use .venv in VS code (windows)
I installed it like that: pip install matplotlib-backend-qtquick

SGaist

Can you provide a minimal requirements.txt to reproduce your environment ?

Using conda with PyQt5 and matplotlib I have in import error but the package is found.
