Closed semikernel closed 7 months ago

Please explain the issue you're experiencing (with as much detail as possible):

At the beginning, I use conda create a new environment and use command:

 pip install -U "manim-slides[pyside6-full]"

I can't use manim-slides in my ubuntu desktop, after "manim-slides BasicExample", it returns:

Could anyone please tell me how to figure that out? Thx a lot!

I uninstalled Qt5 and it works!

Happy it solved your issue!

The issue arose because you had multiple Qt bindings installed, i.e., here you had PySide6 and PyQt5. We use qtpy to choose the Qt bindings, and it gives more priority to PyQt than to PySide. So it was always choosing PyQt5 instead of PySide6.

The best to avoid this kind of issues is to install Manim Slides in a separate virtual environment.
