Without knowing anything about your configuration, my first guess would be that shutdown_on_logout [1] is set to be true.

I'm assuming, based on references to a pod and a pvc, that you're running JupyterHub on Kubernetes. Is that correct? If so, the usual configuration is to mount the persistent volume as the user's home directory. If that's what you've done, only changes to the home directory will persist; changes to any other part of the filesystem will be lost when the container stops. If your Python system is set up to install packages someplace other than the user's home directly, those will be lost when the pod shuts down. If you're trying to solve this in general, you'd need to adjust your singleuser image to make installs go somewhere in the home directory. But if you're just trying to solve it for you, I'd recommend making a virtual environment in your home directory and installing the packages you need within that virtual environment. (Note that you can install and register an ipython kernel within that environment, so that you can run notebooks within it.)
