This is super helpful. Any chance you could add a license to this for anyone using it verbatim?

Ok added it

In case anyone wants a version that also clears from cached_property declarations on parent classes, use this one instead:

        def invalidate_cached_properties(self):
            for kls in self.__class__.__mro__:
                for key, value in self.__dict__.items():
                    if isinstance(value, cached_property):
                        self.__dict__.pop(key, None)
