4 years ago The last two comments on https://github.com/jupyter/notebook/issues/5093 may give you what you need. If that works out, please close this issue - otherwise provide the more recent traceback. This is usually an issue with the argv entry in the kernel definition referencing a command that no longer exists (due to uninstall or move, etc.)
I was trying to Q# when I opened juypter notebook with Anaconda Powershell Prompt. After i opened juypter notebook , my kernel is dead.
