I’ve posted this on the github issues page, so I’m not sure of the cross-posting etiquite… but maybe the Discourse server has more engagement than the issues page. anyway…
I have created a python environment with JupyterHub, and all of its support packages, installed. My goal is to keep this environment “clean”, with only Jupyter/JupyterHub-related packages installed, so I carefully manage updates and deployment.
I have added a couple other kernels to the kernelspec list that are to be used by my JuptyerHub end-users for particular use-cases, particular versions of python, etc. All of these kernels are available in the Jupyter Lab launcher for the user to select, and all are listed here:
jupyter kernelspec list
Available kernels:
python3 /home/<snip>/miniconda3/envs/jupyterhub/lib/python3.7/site-packages/ipykernel/resources
datascience /home/<snip>/miniconda3/envs/jupyterhub/share/jupyter/kernels/datascience
py27 /home/<snip>/miniconda3/envs/jupyterhub/share/jupyter/kernels/py27
I would like to remove the “base” python3 kernel from the JupyterLab Launcher, since this kernel is not intended for general purpose use, and doesn’t contain any useful packages for end-users. But juptyer won’t let me remove that one, presumably because it’s the built-in, default kernel.
jupyter kernelspec remove python3
Couldn't find kernel spec(s): python3
Is there any way to remove this kernel from the kernelspec, or otherwise hide it in the Launcher so users can’t select it?
