ModuleNotFoundError: No module named.....' error while running the pytest in other directory

Question

I'm using Python 3.7.5 and pytest 7.0.1 on Linux. I am writing unit test cases of my project in /tests directory and executing it by following command parent directory, it ran successfully.

python3 -m pytest tests/xxx/test_xxx.py

However, when i copy the same script in /pytest directory and ran the same script again, it ended up with an error.

python3 -m pytest pytests/xxx/test_xxx.py

Error:

ImportError while importing test module
'/projects/db/analytics/advanced_analytics/advanced_analytics/pytests/xxx/test_xxx.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback: /opt/python3.7/lib/python3.7/importlib/__init__.py:127: in
import_module
return _bootstrap._gcd_import(name[level:], package, level) pytests/xxx/test_xxx.py:21: in <module>
from myproject.my_project import my_project my_project/my_project.py:13: in <module>
from advanced_analytics.framework.CICLogger import CICLogger  E   ModuleNotFoundError: No module named 'advanced_analytics.framework'

Please note my_project , /tests and /pytests are created in same parent directory - advanced_analytics.

from advanced_analytics.framework.CICLogger import CICLogger imported in my_project.py file

Kindly let me know why this issue is occurring and how to fix the issue.
