Created the “CustomReference” Library and added reference data to “Library.py”. Can't seem to import via any of these import commands. What am I doing wrong? Thanks in advance.
from CustomReference import Library

Hi Postbio
The correct way would be
Start New Discussion 
Back
Reward Discussion

from CustomReference.Library import *Note that the notebook will not refresh and load instantaneous changes, so you should always terminate your notebook instance first, create/edit the python file, rebuild the project and restart the notebook afterwards to load the latest changes.

Hi Louis,
Thanks for the response.
I'm still unable to import with that syntax (I've tried before via “CustomLibrary import * “), even when closing down the notebook and re-starting.
Also tried clicking ”Restart” in the top, along with, clearing cell outputs.
Thanks in advance if you can shed light on this.
Thanks!
Hi Postbio
We can't reproduce your issue. May you attach a backtest with the library file and notebook here?

Hi Louis,
Sure thing. Here's the project.
EDIT: I have no backtests in dropdown, but it's just what you see in the screenshot above and here.
ps. It's just the most basic importing.
I am having the same issue, same error and setup looks the same. Library import works in main.py but not in any notebook.
Hi Postbio and Mr. B
The custom files/folders were outside the project directory, so they won't get compiled. Please put them under `\project`.

Hi Louis,
Works!
Didn't know it was possible to create & use a folder at the project level like that.
Also thought we had to import by choosing from the dropdown on the left column.
