Remove the kernel on a Jupyter Notebook

How can I remove a kernel from Jupyter Notebook?

I have an R kernel on my Jupyter Notebook. Recently, the kernel always dies right after I open a new notebook.

Solution

  • Run jupyter kernelspec list to get the paths of all your kernels.
    Then simply uninstall your unwanted-kernel

    jupyter kernelspec uninstall unwanted-kernel

    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
