I've been using vscode with Jupyter notebook extension (now maintain by Microsoft) for two years but It's weird to encouter the problem never met before as the error said:

Error: Session cannot generate requests

The problem shows when I train the CNN model. The model I've built previously bumped into this problem, but it works fine when preparing other deep learning models. What I've tried:

1. Install anaconda, use its kernel.
2. re-install Jupyter notebook extension and re-open vscode.
3. run vscode as administrator.

All of them get no luck. The script has been tested and run sucessfully on Google Colab, and it's the alternative I am using now. Is there any way I can fix it?

Other information:

1. windows 11
2. vscode version: 1.62.3
3. jupyter notebook extention: v2021.10.1101450599
4. anaconda with its Python 3.9.6 version package
5. Python(self-installed): 3.9.7

I'll provide extra information if necessary. Thanks.

It's likely your kernel is crashing for some reason. Can you log an issue here? https://github.com/microsoft/vscode-jupyter/issues.
