How to change the name and logo of the default kernel in jupyterlab

[Konstantin Markov]

Hi,

I would like to change the name (Python 3) and the logo (the Python logo) of the default python3 kernel which show up in jupyterlab's launcher. A dirty way to change the name is to edit ''conda/share/jupyter/kernels/python3/kernel.json'' file, but I don't like it. What's also confusing is that after changing the logo files (log-64x64.png and logo-32x32.png) in the same folder, the python logo is still showing up.

If I add a new environment, I can set the kernel's name with 

python -m ipykernel install --user --name mykernel --display-name "MyKernel"

but again, changing the logo files in "$HOME/.local/share/jupyter/kernels/mykernel/" has no effect.

Any help is appreciated.

Thanks,

Konstantin

I'd guess the browser is caching the logo files from before you changed them.
