"AttributeError: 'SubGraph' object has no attribute 'create_parse_func'" when installing PyMedTermino2

[Szlemens0]

When following the installation guide for PyMedTermino2 (https://owlready2.readthedocs.io/en/latest/pymedtermino2.html), Python gives me the following error:

---------------------------------------------------------------------------

AttributeError: 'SubGraph' object has no attribute 'create_parse_func'

I am using owlready2-0.41, Python 3.10.8 and the umls-2022AB-metathesaurus-full.zip UMLS data.

Downgrading to owlready2-0.40 fixed the problem.
