ModuleNotFoundError：没有命名的模块 - Python

Question

Can someone please help with this error? I have tried all sort of ways to import a module in Python but not has worked so far. I have this directory structure below:

|__folder1:
|      |__folder1a
|          |___inner_file.py
|__outer_file.py

I want to import a Class from the outer_file.py into the inner_file.py . However, I have been getting the error ModuleNotFoundError: No module named .

I have tried all the options in this link on GeeksforGeeks . Thanks.

easy

import sys,os
BASE = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, BASE)
