> - Jupytext should set a kernel when doing to conversion of .py to .ipynb. Currently I have to specify it manually. I will work on that at mwouts/jupytext#230. :+1:...

Sorry missed this thread update earlier @mwouts . I think expanding the io handler to capture more situations natively sounds reasonable. The linked code is a bit hacky and could...

Check your `whereis papermill`. I am guessing your python paths aren't consistent and your kernel is running in a different environment. You can also add a print statement to list...

For the second printed error, it looks like the local variable inside your notebook is `None` when you expected to to have a value, which means it's likely unrelated to...

Right, but the error message is still isolated to inside your code. That looks like the right kernel provided your notebook is using a `python3` kernel in it's metadata. Given...

Likely you're hitting the issue that the classic UI does not get any updates these days. It doesn't support some of the newer format spec options like `source_hidden`. Jupyter Lab...

As context the decision was keep-it-simple-stupid as more complex or normalized options would be challenging to integrate with existing UIs / interfaces. It also means it's easy to identify everything...

The pattern suggested seems reasonable. I'm tied up in a few other threads atm, but I think we could continue the conversation around a PR if someone wants to take...

I'd still hesitate to add multiple parameterizations for the reasons listed earlier in the thread. That being said how would you think it should look as an interface / reference...

FYI https://airflow.apache.org/docs/stable/howto/operator/papermill.html is used a lot to have DAGs executing individual notebooks if you haven't seen it. Glad the parameterization for papermill worked well for you. We do a similar...
