Hi @dvmorris, Indeed, the runtime doesn't need to be restarted, because Colab now has the latest version of google-cloud-aiplatform pre-installed (1.25.0) already. However, for future-proofing, it's still safer to keep the restart runtime in the notebook (which we're also including in all of the other notebooks too).

I meant that Colab surfaces a restart button, in the console output, so you don't need any custom code to restart the runtime. I provided a screenshot in the pull request description above.
