Packages such as tqdm will not work with the latest version of IPyWidgets 8

Explore supporting IPyWidgets 8

Work around - Please install ipywidgets==7.7.2

Answer 1 · 2022-03-08T02:43:10.000Z

Is this a difficult issue to resolve? Do we know what causes the widgets to not display at all?

Answer 2 · 2022-03-08T03:35:57.000Z

know what causes the widgets to not display at all?

we need to update the npm packages used and tweak a few places accordingly

Answer 3 · 2022-03-10T05:27:13.000Z

Is there a temporary workaround which might allow this to work while a permanent fix is being worked on?

Answer 4 · 2022-03-10T05:53:16.000Z

temporary workaround which might

unfortunately no. you can use the older version. i don't think 8 had been released yet.

Answer 5 · 2022-03-10T06:26:11.000Z

All good! While version 8 is not yet marked as stable, it has been available on pypi as a pre-release since February 2020, and the first beta (?) appeared in November 2021. There's a few things I'm looking forward to use once it works well within VS Code 😄

Answer 6 · 2022-03-24T06:24:40.000Z

Just as a friendly FYI: The first release candidate for 8.0.0 was released on 12 March.

Answer 7 · 2022-03-30T20:40:43.000Z

@JP-Ellis please test the latest pre-release version of the extension, it should work as long as you are not using any of the latest IPyWidget 8.0 widgets/features. I.e. older widgets like slider/textboxes, etc and othe 3rd party widgets will now work when installing ipywidgets 8.0.

Answer 8 · 2022-04-01T01:55:25.000Z

Unfortunately it didn't seem to work for me. I tested the HTML and Dropdown widgets from ipywidgets v8.0.0rc0 and against v2022.4.1000912146 of the extension and nothing showed up. Let me know if there's anything specific you would like me to try or output you wish to see.

Answer 9 · 2022-04-05T01:40:48.000Z

Will test, I tried this with the 8b1, not the rc version.
Confirmed, it widgets still do not render in IPYWidgets 8 (there must have been some protocol change in the RC version)

Answer 10 · 2022-04-05T17:16:23.000Z

@JP-Ellis
I've just tried this again against the latest pre-release and the v8.0.0rc0 and it seems to work for me
Here's the version of Jupyter extension installed v2022.4.1000971004, please could you let me know if this works?

Answer 11 · 2022-04-07T19:12:53.000Z

Found that slider widget works and not the textbox. Will need to dig deeper into this.

Under the pre-release version of Jupyter plugin (v2022.8.1002431052), running code:

import ipywidgets as ipw
ipw.Text(value="test")

nothing presented.

FWIW, ipywidgets version 8+ is now in conda-forge (and has been so for a month or so), so anyone who uses vscode with conda environments that specify conda-forge as a channel will be pulling in 8.0.2 by default these days.

E.g. conda create --yes --name tqdm-trouble-cf -c conda-forge python tqdm jupyter will create an environment in which tqdm won't work anymore on vscode (though some of the older widgets like IntSlider do still work).

Simple repro:

from tqdm.auto import tqdm
for i in tqdm(list(range(10))):
    print(i)
# nada

from ipywidgets import IntSlider
IntSlider()
# works

Anyway, just posting this as there are going to be more folks with weird widget failures now that ipywidgets 8+ is starting to trickle into common package sources...

Answer 14 · 2022-10-01T02:45:20.000Z

I had to pin ipywidgets to the previous generation in my install scripts, or else VSCode would fail. This is annoying.

ipywidgets==7.*

Answer 15 · 2022-11-06T21:01:43.000Z

Required work to get this working in VS Code:

Support running kernel startup code prior to synchronizing kernel messages with webview kernel
- Buffer kernel messages, see work done in lazy creation of controllers (switching controller from remote kernel spec to live kernel spec)
Support lazy loading of IPyWidget script instead of statitcally contributing this in controller
Support querying version of ipywidgets
Create a loader script that will load version 7 or 8 of ipywidgets
- Careful thought needs to go into designing this (see last point)
Publish IPyWidget npm package as version 7
- Plan is to eventually create a seprate branch for v7 after publishing to version 7 (consider this new branch as the branch for maintenance of the older version, hopefully no more changes here)
- The main branch will subsequently be used for version 8 & the new version of npm will be version 8
Pull in the npm package version 7 into Jupyter extension
Review the renderer script, we might need to make some changes there for
- #8635
- For loading existing widget state from notebooks
- This will probably end up pulling in be the loader script in some form that loads version 7 or version 8 of the widget script

Challenges:

When opening an existing notebook we need to determine the version of IPyWidgets to use
- Check the modules and version, if we have any modules that start with @jupyter-widgets/ and have a version >= 2, then assume its IPyWidgets 8. Else 7
- If we cannot find such widgets,
  - Send telemetry for this, to see how often users will fail to load widgest
  - Can we Assume IPyWidgets 8
- We might not be able load any random script without knowing the version of IPyWidgets in kernel. If we load 7 and the user runs a cell and then we find out that 8 is required, we now need to re-initialize everything with version 8.
- Hence if we have no idea what the version is, we will not load any widget script (for now)
- TODO: Find out if we can re-factor widget scripts and toggle the script versions, i.e. reload another version.
Accessing ipywidgetsKernel?.renderOutput in the renderer script would have to be async, as we'd need to wait for the widgets scripts to load.
- The loader script could optionally expose this function, which would internally load the necessary script and then make the call into the loaded script.

any update on this?

Answer 17 · 2023-01-20T03:44:27.000Z

I just ran into the same. It took me a while to debug and just found out the ipywidgets 8 does not support VS Code.

Answer 18 · 2023-02-06T18:26:40.000Z

For the folks asking for updates, @kieferrm posted that "Support ipywidget 8 #8552 @DonJayamanne" is on the planning for February 🎉

This is great! I keep getting questions from colleagues about why their widgets aren't working in VS Code 😄

Answer 19 · 2023-02-10T06:03:10.000Z

Nice, so that it will work out of the box now? or we need to install update something?

Answer 20 · 2023-02-10T06:17:23.000Z

Please wait till early next week and it will work in a prerelease version

Answer 21 · 2023-02-10T15:21:44.000Z

@matifali you should be able to test this within an hour
Please install the pre-release version of the Jupyter extension and the latest version of the notebook renderer application in vscode insiders

Answer 22 · 2023-06-16T05:40:22.000Z

@DonJayamanne Do you know when we can expect the fix to this being available in a released version of this extension? That would be very much appreciated! Thanks for fixing this :)

Answer 23 · 2023-06-16T05:43:04.000Z

We generally close issues when it’s been resolved
If not resolved and cleared then we add comments to that effect
The support for ipywidgets 8 was added a few releases ago

Answer 24 · 2023-06-16T05:48:41.000Z

Got it, thanks a lot! I think I got confused with the old version that was released on https://github.com/microsoft/vscode-jupyter/releases/tag/2022.09.120 -- it seems on the marketplace a newer version is available. Thanks for your help and sorry for the confusion :)

Answer 25 · 2023-06-16T05:50:01.000Z

It looks like this issue was tricky to fix, kudos for getting it solved!
