Where are you running your code from and what is your PYTHONPATH envirnoment variable set to? Do you have an `__init__.py` file in the `apps` directory? — Tom Dalton, Feb 24 '21 at 15:14

What I have done in situations where I am facing import issues like that. I use sys module and append the directory that contains the package I need to import (test2.py in your case) to the paths that python will check when looking for files as you try to import.

So something like that

import sys
path_to_project = '/path/to/project/apps/'
if path_to_project not in sys.path:
   sys.path.append(path_to_project)

from test2 import function2

tried ..test2 and got an ImportError: attempted relative import with no known parent package – Sri hari Feb 24 '21 at 15:25
@Srihari Yeah, sorry, I think the relative import method won't work here, the first one worked for me when I tried it though. – djvaroli Feb 24 '21 at 15:26
