Imported python package unrecognized submodule

Question

I am unsure why when I run the command openstack, I get this error below, when the openstackclient.shell submodule is supposed to come with the python-openstackclient package:

Traceback (most recent call last):
  File "/usr/bin/openstack", line 5, in <module>
    from openstackclient.shell import main
ModuleNotFoundError: No module named 'openstackclient.shell'

I followed this documentation (Link to python-openstackclient package), I ran this command: pip install python-openstackclient

And I can confirm it is installed with sudo pip list in my SUSE machine with python3
