Hi Martin,
The following code in your example is obsolete.
/concurrent/qprocess.py:83: DeprecationWarning: QProcess.start(const QString & command, QFlags<QIODevice::OpenModeFlag> mode) is deprecated
self.p.start("python dummy_script.py")
I have checked the documentation at Qt, it also said obsolete but did not suggest replacement. Do you have an updated code?
I am running PySide2 version 5.14.2.1
and Python 3.7.6
Thanks
