I am trying to change my code from PyQt5 to PySide2. Most of the my scripts I simply have to change imports from PyQt5 to PySide2 and it works the same. However I tried to rework the licensewizard example in the Qt documentation from PyQt5 to PySide2. In PyQt5 it works perfectly, However, in PySide2 I get a error with exit code 139 (interrupted by signal 11: SIGSEGV). The PySide2 qwizard code for linear wizards like the class wizard example, works fine. Does anyone knows why it fails with the non linear wizards and why I get that error?
Thanks
The code below works for PyQt5. Replacing PyQt5 with PySide2 I get an error
Process finished with exit code 132 (interrupted by signal 4: SIGILL)

It seems that unlike PyQt5, PySide2 requires that you pass a parent, in your case the solution is to change the constructors of the classes:
class Some_Page(QtWidgets.QWizardPage):
def __init__(self):
super(Some_Page, self).__init__()
to:
class Some_Page(QtWidgets.QWizardPage):
def __init__(self, *args, **kwargs):
super(Some_Page, self).__init__(*args, **kwargs)
When we add a page, we pass the parent to him:
class Wizard(QtWidgets.QWizard):
num_of_pages = 5
(intro, class1, class2, class3, conclusion) = range(num_of_pages)
def __init__(self, *args, **kwargs):
super(Wizard, self).__init__(*args, **kwargs)
self.setPage(self.intro, IntroductionPage(self))
self.setPage(self.class1, ClassesPage1(self))
self.setPage(self.class2, ClassesPage2(self))
self.setPage(self.class3, ClassesPage3(self))
self.setPage(self.conclusion, ConclusionPage(self))
self.setStartId(self.intro)
