python django smart-selects is not working properly

Question

I have install django-smart-selects but when i add the url in the urls.py

url(r'^chaining/', include('smart_selects.urls')),

when i run my application after this i got this error

from django.utils.encoding import force_text ImportError: cannot import name 'force_text' from 'django.utils.encoding'

so here in django.utils.encoding I didn't find any import force_text so I change it to force_str.

I am using django 4.0
