Hi All, I'm new to prefect and after making a few refactoring to my existing flow.py. Initially, the folder structure looked the following and it was getting registered successfully (

prefect register --project my_project -p bar

)

foo_root_folder
├── README.md
├── bar
│   └── flow.py
├── pyproject.toml
├── requirements.txt
├── setup.cfg

Since the file

flow.py

was cluttered with all utils functions required for the flow execution I refactored it into a separate python package and made calls to those functions in

flow.py

from bar.utils import get_some_useful_function

The resultant folder looked like the following:

foo_root_folder
├── README.md
├── bar
│   ├── __init__.py
│   ├── utils.py
│   └── flow.py
├── pyproject.toml
├── requirements.txt
├── setup.cfg

When I try to register now I am getting error as

ModuleNotFoundError: No module named 'bar'

Can anyone please let me know if anyone faced similar issues before and how they resolved it? Thanks

Hi @Dev Dasgupta, all storage just keeps the Flow file except for Docker storage. In order to package these custom modules, you need to add them in a container.

I see. Thanks, @Kevin Kho
