Random AssertionErrors & Output stops working #162

Closed trueToastedCode closed 1 year ago

trueToastedCode commented 1 year ago

Describe the bug Followed the latest installation instructions and my notebooks keep getting assertion errors... usually combined with the notebook stops working (code executes but it won't output anything anymore). I've changed the Python version from 3.10 to 3.8 which helped a lot with the frequency but it did not fully solve the issue.

Uncaught exception, closing connection.

My apologies, but I do not have the bandwidth to assist with individual installation issues. If you've found a bug in a specific notebook I am glad to investigate and resolve.

Alright thx for noticing, no problem. If anybody should encounter the same issue... found the issue as well in https://github.com/microsoft/vscode-jupyter/issues/12775 (although i did not use VSCode but the error seems to be identical) Like mentioned there, downgrading some of the packages solves the issue (for now) 👍
