Silencing "a jupyter kernel connection is required..." message

[agahkarakuzu]

Hi!

I was wondering if there is an option to suppress this message in an output rendered through MyST:

thebe/packages/core/src/utils.ts

Line 29 in 2f69ba2

<div class="thebe-ipywidgets-placeholder-message"><code>ipywidgets</code> - a Jupyter kernel connection is required to fully display this output.</div>

For a cleaner look, I want to add this information in the figure caption and suppress from the output (if possible).

Thank you!

Hi @agahkarakuzu, one way to suppress the output is to add a placeholder to the figure, that should/would remove that message. And it will look nicer/cleaner in the process - https://mystmd.org/guide/reuse-jupyter-outputs#placeholder-content - does that fit your use case?

Hi @stevejpurves, thanks for responding! I already have an interactive figure (widgets are modifying traces on it when connected to a kernel) rendered from the labeled cell output at the initial values of the sliders, and the warning appears right below it. So I assume using a placeholder would remove the content of interest?

[stevejpurves]

@agahkarakuzu it would replace the entire contents of the figure (all cell outputs) only on initial render, as soon as you connected to a kernel and ran the figure (cell/notebook) it would be replaced with your widgets.

It sounds like your cell might be producing 2 outputs though? the first an interactive graph that does not require a kernel and the second containing widgets? [in which case the placeholder is not going to cut it, it would if your passive render was a static image]

[agahkarakuzu]

The widget callback is creating/updating the interactive figure.

This is how it looks on the page:

and on the notebook:

with the following input:

#| label: interactCylinder

@interact(Ncyl=widgets.IntSlider(min=1, max=100, step=1, value=30,description="# cylinders"), R=widgets.FloatSlider(min=0.5, max=5, step=0.5, value=1.5, description="R cylinder"))
def update(Ncyl, R):
    """Update the visualization based on widget values."""
    visualize_random_cylinders(Ncyl=Ncyl, R=R, L=100)

[stevejpurves]

yes I thought so. I take it you would also want to remove the interactive(children=...?

so it looks like this line in the https://github.com/jupyter-book/myst-theme/blob/50c625864f091f52dc563cd3bd486e68de3625d1/packages/jupyter/src/jupyter.tsx#L90-L91 @myst-theme/jupyter package is the culprit but there's no configuration available for that right now, seems like it could be a "theme option" which would then need to be propagated through, to the PassiveOutputRenderer.

it might be better to wait on jupyter-book/myst-theme#429 though.!?

Thank you so much for the clarification!

I'll keep an eye on this PR as it is not really urgent and pretty glad to learn about rehydration through a PR :)

great, closing this for now then
