I am working with odx files and I have a generate.py file to run. I am using pyXB. When I try to run I am getting this.

*Traceback (most recent call last):
File "C:\Users\rohitkr\Downloads\starter_kit_adas-master\starter_kit_adas-master\devops\scripts\generate_odxf\generate_odxf.py", line 15, in

What could be the problem? Thanks in advance.

In python 3.10 MutableSequence was removed from collections in favor of collections.abc

Deprecated since version 3.3, will be removed in version 3.10: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they continue to be visible in this module through Python 3.9.

>>> from collections import MutableSequence
Traceback (most recent call last):
  File "C:\Program Files\Python310\lib\code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>
ImportError: cannot import name 'MutableSequence' from 'collections' (C:\Program Files\Python310\lib\collections\__init__.py)

>>> from collections.abc import MutableSequence

If you don't want to change the source code, there is an easier way. Just use this in your script after importing.

import collections
collections.MutableSequence = collections.abc.MutableSequence
