As setup.py doesn't specify an upper limit on Django compatibility and DjangoCMS currently supports Django 3.0.x, I encountered this compatibility error on installing version 1.6.1 of django-cms-articles just now.
ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding'
This looks to occur in most of the model files initially, though I haven't looked further afield yet.
