HoloViews/ hvplot not working in code-server Jupyter Notebook on Binder

[MarcSkovMadsen]

I'm trying to create a nice repository for me and Sophia M Yang for a blog post and tutorial. I would also like to show case that the HoloViz ecosystem works with VS Code. So I added the code-server to the Binder environment.

Unfortunately it seems not to work

Repo: https://github.com/MarcSkovMadsen/hvplot_interactive commit 3cd8bf19dc326a76efe20e2dd3fedb7f1ff6e6af

• Open https://mybinder.org/v2/gh/marcskovmadsen/hvplot_interactive/3cd8bf19dc326a76efe20e2dd3fedb7f1ff6e6af
• Open VS Code
• View Output - Jupyter to see log message
• Create a new notebook
• Make sure the kernel is notebook

print('hello')

import hvplot.pandas

Notice how it took a long time to execute this cell

print('hello')

Notice the console how you get an error message as you print hello.

import holoviews as hv

hv.extension("bokeh")

In the video this load pretty quickly (8secs) but I've also experienced it running for minutes before I've given up.

import panel as pn

It stopped working.

Additional Context

• I don't experience the same problems in "real" VS Code on my laptop.
• I experience similar problems on my Jupyter Hub for work where code-server is also running.

Can pure Bokeh plots be rendered in code-server?

[MarcSkovMadsen]

Yes. There seems to be no problem in the interactive window. But the notebook is problematic.

[MarcSkovMadsen]

For me the interactivity in Code is key. It is hard for others to keep up with and compete with that environment. So need to work there.

[MarcSkovMadsen]

This is an example of Bokeh/ Holoviews plots being render in code-server @maximlt . I'm used to having full interactive with 2-way comms in VS Code on my laptop. Here it does not work. But I can get it to render in the Interactive Interpreter. In the Notebook everything gets too slow.
