How to use python 3.9.12 kernel and up

How would i modify this to run 3.9.12?

I have noticed that init.sh and environment.yaml files are created speperately for each notebook. How can I keep the same environment with python 3.11 for all notebooks in a given wrkspace?

To achieve that you just need to move your init.sh file to the workspace files folder:

To apply an init.sh script to all notebooks in your workspace, move the init.sh file to workspace files. This will be executing the added file for any notebook in the workspace once it is started.
