@ouliuquan thank you for reporting the issue.

I believe if you follow the notification and open the developer tools you'll see an error regarding notebook support as it is currently not implemented in the framework (eclipse-theia/theia#8395 (comment)).

In addition, there is no version of jupyter listed in the extensions-view given there is no compatible version, are you connected to the public instance https://open-vsx.org/, bumped the default api version or installed the extensions manually?

@vince-fugnitto First of all thank you very much for your help. Excuse me I'm so used to using API 1.75.0 that I didn't realize it. I did upgrade the API, and then I tried the official 1.32.0 (API 1.55.2), and this extension is indeed not recommended.

I am currently doing research on enabling theia to support Python-2021.4.765268190 (the last version without Pylance). I make a discussions on eclipse-theia/theia#11974, I have found that it can support up to this version without the Pylance, but I don't know why it rely on Jupyter, so I also make the open-vsx.org support full Jupyter's package EclipseFdn/publish-extensions#656.

For now, there are still 2 question:

• I hope that the prompt error can be resolved(this issue).
• I hope that I can fix the Run button on 2021.4.765268190 version, the button is post on the discussions Have any plan for support new Python/Pylance extension? theia#11974

Thanks for your guidance, I learned a lot
