Menu
To change the kernel version in Jupyter Python Notebooks follow the steps below : Open the Python Notebook and click on " Kernel " from the menu bar located on top of the python notebook. Click on " Change kernel " from the drop down box that appears and chose the version that is required.
A kernel is a runtime environment that provides programming language support for the Jupyter Notebook application. When you open a Notebook in edit mode, exactly one interactive session connects to a Jupyter kernel for the Notebook language and Spark version that you select.
To interrupt a calculation which is taking too long, use the Kernel, Interrupt menu option, or the i,i keyboard shortcut. Similarly, to restart the whole computational process, use the Kernel, Restart menu option or 0,0 shortcut.
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
You can delete it in the terminal via:
jupyter kernelspec uninstall yourKernel
where yourKernel is the name of the kernel you want to delete.
jupyter kernelspec remove now exists, see #7934.
So you can just.
# List all kernels and grap the name of the kernel you want to remove
jupyter kernelspec list
# Remove it
jupyter kernelspec remove <kernel_name>
That's it.
There two ways, what I found either go to the directory where kernels are residing and delete from there. Secondly, using this command below
List all kernels and grap the name of the kernel you want to remove
jupyter kernelspec list
to get the paths of all your kernels.
Then simply uninstall your unwanted-kernel
jupyter kernelspec remove kernel_name
