Python: can't open file '/home/user/manage.py': [Errno 2] No such file or directory

Django

I’m on Celery and Windows section and I followed the steps in the attached PDF file,
When I ran pipenv install, I got the below display

Installing dependencies from Pipfile.lock (16c357)…
:snake: ▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉▉ 0/0 — 00:00:00

The pipenv shell worked well, but when I then ran python manage.py migrate and python manage.py seed_db, I got the below error message

python: can’t open file ‘/home/user/manage.py’: [Errno 2] No such file or directory.

I feel, from my point of view, the dependencies project (Pipfile.lock) seems empty 0/0 -00:00:00.
Could that be the problem? I cannot say. I just need a way out guys. PLEASE
Thanks.
