VS Code Insiders cannot open notebooks

[rchiodo]

Notebooks broken in insiders

Since this version:

VS code insiders is making breaking changes to the proposed API the jupyter extension uses to open notebooks. Until we can get a new build out, we recommend going back to stable.

This issue will track our progress on making a new build just for insiders.

You can also go back to an older build of insiders if you want to continue using it. See directions here on how to do that:

You can also go back to an older build of insiders

The previous Insider version 1.53.0 works, which can be downloaded from https://vscode-update.azurewebsites.net/1.53.0-insider/win32-x64/insider (for Windows).

In settings, search "update: Mode" and set it to "manual" to disallow automatic update. Different versions of VS code can co-exist but you need to start the specific version by double-clicking Code - Insiders.exe in the specific folder.

For Apple Silicon Macs, the link you want is https://vscode-update.azurewebsites.net/1.53.0-insider/darwin-arm64/insider (it took me a few minutes to figure that out, so maybe that'll help others)

[rohan-paul]

For Linux (Ubuntu 20.04), got the .deb file for 1.53.0 from here.

vscode-update.azurewebsites.net/1.53.0-insider/linux-deb-x64/insider

[frenkcleven]

For completeness: 1.53.0 Insider build for Intel Macs.

[taisbak]

You need to add -user to the download url if vscode is installed without local admin rights using user set-up, e.g.:
https://vscode-update.azurewebsites.net/1.53.0-insider/win32-x64-user/insider

[DonJayamanne]

Just an update, we are looking into this, and aware of the issues.
The Insiders Notebook API has changed significantly and are in the process of updating the code accordingly.
& I'm sorry for the inconvenience

Same issue - for now I'm working with the normal VSCode where notebooks are running.

[DonJayamanne]

A new extension has been published to the marketplace with the fixes.
Please ensure you update to the latest version of VS Code insiders & the latest version of the Python extension 2021.3.xxxx

[DonJayamanne]

Moving to validate

[rchiodo]

For me I had to update the juypter extension and reload VS code for this to work with VS code insiders.

[rchiodo]

Nope sorry still not working. See this issue:
microsoft/vscode#117445

It works partially now. If you use the 'Open With' editor you can open a notebook in insiders again:

Same for me. But at least this is usable for now. Thanks!

[AndrewLaganaro]

Returned to 1.53.0 version on windows 10, also rolled back the jupyter extension which has also previously been updated and eveything got to work back again. Also turned off Vscode auto update and python auto update too for a while.

[gusbemacbe]

After updating the Python extension and reinstaling the @DonJayamanne's VSIX extension, the Jupyter notebooks work here on VSCode 1.54 now, but I receive two errors from Python extension:

[rchiodo]

Sorry but you also need the insiders version of the python extension. It has similar problems with the API.

You can do this automatically with this setting here:

It worked now, thank you!

Too bad that VSCode Insiders with Jupyter Notebook (even if I always trusted the notebooks) does not support Jupyter Notebook's Python Markdown extension.

@gusbemacbe Do you want to log a suggestion for this?

Yes, I refer to the https://jupyter-contrib-nbextensions.readthedocs.io/en/latest/nbextensions/python-markdown/readme.html.

[virtu]

After upgrading, notebooks are no longer detected but displayed as plain text in VSCode insiders. Any suggestions?

[jeanga]

Right click & "open with" did the job for me.

Thanks! Should be fixed, though, so the regular approach works again.

[eduardopaul]

Working like a charm! Thanks all for the amazing extension. Do you have any idea when this new notebook interface should be released in VSCode's regular version?

Yes it does! Thank you.

[marcbernot]

Thanks notebooks work in 1.54. Is the live sharing of notebooks supposed to work? I never managed to get it working. Tips would be appreciated

Live share of notebooks is a work in progress. You can track that here I believe:
microsoft/live-share#3301
https://docs.microsoft.com/en-us/visualstudio/liveshare/reference/notebooks

[rchiodo]

I'm closing this bug as the latest VS code insiders and the latest Jupyter extension and latest python insiders extension all seem to be working.

Going forward we hope to be able to ship the jupyter extension more often to deal with breaking issues from VS code on a much quicker cadence.

Thanks for your patience.

[rchiodo]

Do you have any idea when this new notebook interface should be released in VSCode's regular version?

@eduardopaul this is actively being pursued. We're working on testing it with a few customers first to see how the new version compares to the old one. Right now your best bet for using the new interface is to use the insiders version.

[gusbemacbe]

@rchiodo, and Jupyter Notebook's Python Markdown extension?

[rchiodo]

@gusbemacbe I suggest you log a new issue for the markdown extension. Until that happens we won't be able to tell how many other people want it. Meaning right now it's not planned at all.
