Jupyter notebook through VSCode Remote session not updating animations

[guidocioni]

I'm not sure if I'm doing something terribly wrong but I just tried to create an interactive plot with a time slider using the xarray accessor and, when moving the slider, nothing is happening and the plot does not update.

Then I went on the official guide webpage (https://hvplot.holoviz.org/user_guide/Interactive.html) and also here nothing is happening to the plots when I change sliders or dropdown state...
Aren't they supposed to update?

Also tried to change browser without success.

Pretty sure I'm missing something simple here...

Hi @guidocioni

Plots with widgets on the website are not interactive as our Project does not have the resources to run a live server.

Regarding your example please share a minimum, reproducible example. Thanks.

That makes sense

Sure thing, but honestly there is nothing complicated going on here.
I'm just using this code

import hvplot.xarray
import xarray as xr

ds = xr.open_dataset("test.nc")
ds.smlp_anomaly.hvplot(
    groupby="time",  # adds a widget for time
    clim=(-3, 3),  # sets colormap limits
    widget_location="bottom",
)

You can download the test.nc file here: https://cdn1.meteonetwork.it/models/malawi/wnetwork_new/test.nc

In my case, if I try to interact with the widget the date and the data of the plot never changes.

Sorry, I may have an idea of what the problem is.

I'm running this code into a jupyter notebook over a remote connection in Vscode.
When running locally and remotely with a tunnel to my local browswer I was able to get the expected behaviour (animation updating).

There may be something going on in the way Vscode is rendering the widget over the remote connection...

I went through this https://discourse.holoviz.org/t/problems-with-tabulator-widget-in-vs-code-jupyter-notebook/5454/12, which seems exactly my same issue, but I do have panel, jupyter_bokeh and the other requested packages up to date.

Any idea what could be the conflict when running the notebook through Vscode?

It's quite possible that this is the same issue that was fixed here: holoviz/panel#5201

Could you make sure you have Panel >=1.2.0 and give us a breakdown of your environment?

let me know if I can provide you with more info to debug the issue

Can you try upgrading holoviews to 1.17?

[guidocioni]

Hi all, I just upgraded holoviews, hvplot, jupyter_bokeh and Panel to the latest version but the problem still persists...

[guidocioni]

Wait, I just restarted the vscode server and it seems to be working now! :)
Yeee
