Importing py from sibling directory gives Attempted relative import in non-package error

Question

I've been searching on stackoverflow and can't find out what's wrong.

My directory structure is as follows:

--project
  --__init__.py
  --helpers
    --__init__.py
    --functions.py
  --set1
    --__init__.py
    --foo.py
  --set2
    --__init__.py
  --setn
    --__init__.py

In foo.py I want to import functions.py I do this with

from ..helpers import functions

And this is giving me the error:

Attempted relative import in non-package error

All of the answers I've found so far deal with setting up init.py properly.

You need to use from project.helpers import functions, you're not actually using your script as a package. See her for more info: How to fix "Attempted relative import in non-package" even with __init__.py
