I am having the exact same issue. I tried downgrading Jupyter to the previous version, and it still did not work.

[JunbeiZhang]

me too, I try to reload it, but still can't work.

[DonJayamanne]

I'm sorry you are running into this,
@sbroth @JunbeiZhang Please can you disable all extensions and try this again.
Also, can you search for the ipynb extension and ensure it is enabled, see below on searching for this.

[JunbeiZhang]

I try jupyter again with and without extensions, making sure .ipynb support is ok. But I still can't use it, it comes the same error.

Hi @JunbeiZhang @sbroth,
Try switching to a pre-release version for the Jupyter extension pack [v2024.4.2024042601 (pre-release)] in VS Code. That worked for us!

[jeet183]

Thanks @jinang99!
This worked for me as well.

[DonJayamanne]

If this issue still persists, please ping here or feel free to create a new issue.
Closing as I think this no longer exists.

I'm still facing the same error:
When I use: jupyter:export current python file as jupyter notebook,
I got:

Extension 'vscode.ipynb' is not known or not activated

I checked the versions below, but they didn't work (I got the above error)

• v2024.8.2024080201 (pre-release)
• v2024.7.0
• v2024.4.2024042601 (pre-release) <- Even though jinang99 succeeded with this version, I still got the error.
• v2024.3.0

The following versions work fine:

• v2024.2.2024022602 (pre-release)
• v2024.2.0

I suspect something was changed between these versions...
