Description
I often install kernels from project virtualenvs (my-project/.venv/
) that eventually get removed. I can manually remove a kernelspec with jupyter kernelspec remove my-project
but forget to do this, then forget the missing kernel name, etc. Instead, I use a script that checks if the python executable the kernel points to exists, and if it doesn't, removes the kernel. A command jupyter kernelspec remove --missing
would save users (myself) some pain.
Alternatively, it might be simpler to add jupyter kernelspec list --missing
which would list out kernels with missing python interpreters, and a user can pipe this to jupyter kernelspec remove
.
I'd be happy to attempt a PR with one or both of these features if you agree. Thanks!
