Widget not showing on VSCode with Remote SSH

Hello,

I am on MacOS and using itkwidgets 0.32.0 on VSCode 1.55.2 to work on a remote Linux Server using the Remote-SSH Extension 0.65.1. However, the itkwidget is not showing up in the interactive python console. I set the python.loggin.level to debug, but didn’t see any meaningful errors or warnings in the Jupyter and Python output console.

This here is my test script:

import numpy as np
from itkwidgets import view
image = np.random.rand(100,100)
view(image)

When running the same script locally, without the Remote Extension, the widget is working nicely. It even works, when I connecting to an existing Jupyter server running on said remote Linux Server.

It might not be correlated, but when I tried adding “jupyter.widgetScriptSources”: [“jsdelivr.com”, “unpkg.com”], to the remote ssh settings I got this VSCode warning when running the test script:

Unable to load a compatible version of the widget 'itkwidgets'. Expected behavior may be affected.

Hmm, I think it’s a bit tricky to get it work there, it’s not a normal Jupyter environment as I understand, to get it work we need a way to do bidirectional messaging between the editor and the kernel, plus a way to show the iframe. In the normal Jupyter we used Comm messages, I am not sure if that is available and what need to be adjusted.

I will need to check it out.

seeing a similar thing here. remoting into linux, using itkwidgets.view shows nothing (but no error either):

FWIW: If I click the ... next to where the widget, I have the option to pick a renderer (one shows the text repr, the other shows the empty space)

@thewtex, lemme know if I can help troubleshoot! thanks 😃
