What is a method of installing a Python package scoped at the notebook level to all nodes in the currently active cluster?

AUse &Pip install in a notebook cell

BRun source env/bin/activate in a notebook setup script

CInstall libraries from PyPi using the cluster UI

DUse &sh install in a notebook cell

Show Suggested Answer

Suggested Answer: C

Installing a Python package scoped at the notebook level to all nodes in the currently active cluster in Databricks can be achieved by using the Libraries tab in the cluster UI. This interface allows you to install libraries across all nodes in the cluster. While the %pip command in a notebook cell would only affect the driver node, using the cluster UI ensures that the package is installed on all nodes.

D looks interesting, but I'm not familiar with the &sh command. Might have to do some research on that one.

I'd go with C, using the cluster UI seems like the easiest way to install packages for the whole cluster.

C) PyPi through the UI? Sounds like a fancy way to do it. I'm sticking with the classic A) Pip install.
