Python3 import module error

Question

I have mypackage folder with empty __init__.py and two modules compute.py and config.py . Being in the folder that contains mypackage and main.py , I run python main.py which has from mypackage.compute import myfunction and inside the compute.py there is from config import * . The folder structure is below:

main.py
mypackage
    __init__.py
    compute.py (contains myfunction)
    config.py

Now, when I run python main.py everything works perfectly, whereas if I run python3 main.py , I get:

Traceback (most recent call last):
  File "main.py", line 1, in <module>
    from mypackage.compute import myfunction
  File "/home/myself/Downloads/mypackage/compute.py", line 1, in <module>
    from config import *
ImportError: No module named 'config'

Not quite sure what could be wrong here?

Python 3.x has changed import resolution. You must now specify a full relative import if you want to perform a relative import.

from .config import *
