DonJayamanne commented 3 years ago

I think i know the problem, I hadn't tested this on windows. The kernel is registered with the wrong CLI, I'll be pushing a new version soon.

DonJayamanne commented 3 years ago

Pushed a new version, should be fixed now. Closing this issue. If the issue persists with the new version, please feel free to reopen or create a new issue.
