TypeError: declarative_base() takes 0 positional arguments but 1 was given

Hey there,

i wanted to use cimpyorm to read out some CGMES grid data and modify them in python, but i was not able to run the program. I am using a windows machine with python 3.10.11 and cimpyorm 10.1. When i execute following code:

import cimpyorm

if __name__ == "__main__":
    test2, model = cimpyorm.parse(r"grid_data/Export.xml")

an error occurs. It says:

TypeError: declarative_base() takes 0 positional arguments but 1 was given

as in the Title of this issue. I also checked using python 3.9 and 3.11, with the same results.
