Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

That’s my one repository linked with github. I am able to run Notebook from other folder or directory but getting error when running notebook from this repository. I cloned the same repository to another directory and issue remains.

Thanks for the bug.

It looks to me like the kernel can’t be run by jupyter. If you attempt starting jupyter using the same kernel outside of VS code it might give you more information as to why. To do so you’d:

Go to the directory with the problem in terminal
Run jupyter notebook
Create a new notebook
Pick the python38264bit58e42c9575d24eb58f427896571571af kernel
Look at the output at the terminal (assuming it will fail too)

Additionally if you could set this setting:

That should show a lot more output in the ‘jupyter’ output tab in VS code.
