One good source of information on these topics is the ipykernel
documentation:
https://ipython.readthedocs.io/en/stable/install/kernel_install.html
The main trick is you cannot have several kernels with the same display
name.
Open the file
*/share/apps/platform/ai/py36/3_6_9/share/jupyter/kernels/python3/kernel.json*
and change the kernel's "display_name" from "Python 3" to "Python 3.6".
Then run something like the following:
$ python37 -m ipykernel install --name 'Python 3.7'
replacing `python37` by any suitable way for you to call Python 3.7.
