The dict is added by the Jupyter plug-in automatically. Perhaps the plug-in isn't working. You can manually add the dict with “ploomber nb -i”

ploomber nb -i

works! Thanks.

It's an integration that automatically injects the product variable. It should Install automatically but sometimes it needs extra steps to activate depending on your setup

I have checked the doc. After

jupyter serverextension list

, it outputs:

ploomber enabled
    - Validating...
      ploomber 0.19.6 ok

ploomber jupyter extension should work. But it did not work. Additional

ploomber nb -i

is required.

do you any ploomber-related logs? in the jupyter console (the windows where you start jupyter)

I checked the ploomber-related logs, including: ploomber | extension was successfully linked. [Ploomber] setting content manager to PloomberContentsManager ploomber | extension was successfully loaded. However, it does not work. Neither in a new conda env with only ploomber and jupyterlab. 😟

do you see any other logs when opening a file that is part of the pipeline. Example, try downloading

ploomber examples ml-basic -o example

, then move to the example folder, right click on fit.py then "open as notebook" and see if new logs appear when you click on "open as notebook"

I work on Windows 10. After test

ploomber examples -n templates/ml-basic -o ml-example

in

C:/

and

D:/

drives respectively, I think I can locate the problem. My own code report the same error. In dirve D:/, after "open as notebook", inject cell failed. Errors are:

However, in drive

, with the same code, it works fine.
