I have a Python script that should be started via a batch file, Using Python from the QGIS installation without opening QGIS itself. Unfortunately this doesn't work because I think the Python installation of QGIS accesses the PyQt libraries differently.
What do I have to do so that the script still works via a batch via the QGIS Python installation?
The attached scripts work without any problems on another system that has Python (and PyQt) installed directly. The script without PyQt library also runs via QGIS-Python and Batch.
I use QGIS 3.16 with Python 3.7 and Windows 10 However, installing an “additional” Python version on the system is not an option.
