remove kernel on jupyter notebook
How can I remove a kernel from jupyter notebook?
I have R kernel on my jupyter notebook. Recently kernel always dies right after I open a new notebook.
Answer
Run jupyter kernelspec list to get the paths of all your kernels.
Then simply uninstall your unwanted-kernel
jupyter kernelspec uninstall unwanted-kernel
Old answer
Delete the folder corresponding to the kernel you want to remove.
The docs has a list of the common paths for kernels to be stored in: http://jupyter-client.readthedocs.io/en/latest/kernels.html#kernelspecs
