Well, I am trying to run my django project in new environment, I installed all of my requirements although every package is installed but it is still giving me below mentioned error. I am not sure but I am guessing it is due to version conflict of some modules.
I looked for existing solutions or someone who faced similar situation but no success.
the Random method is located in django/db/models/functions/math.py . change your import statement to this :
from django.db.models.functions.math import Random
