I'm a beginner organizing my code properly in python and I am struggling a bit doing imports in my main .ipynb from a .py script.

My folder is organized as it follows:

|   naive.ipynb
|   requirements.txt
|
+---data
|       DNA_train.txt
|       pseudomona.feather
|       pseudo_test.csv
|       pseudo_train.csv
|
+---model
|       dna_token.model
|
\---src
        token_dna_converter.py
        __init__.py

As I have read, to be able to import classes from a different folder, I should add a __init__.py file to able access from a super folder. In the __init__.py I put the following:

from .token_dna_converter import tokenDNA

Afterwards, I want to call this script in a notebook and I have tried the following:

from token_dna_converter import tokenDNA

However, the .ipynb does not detect this inner "package"... I don't know why and I am struggling to try to fix this.

Does anyone know how should I properly call this script? I would appreciate everything!
