This document describes how you can use Gemini in Colab Enterprise, which is a product in the Gemini for Google Cloud portfolio, to help you explain code cells in a Colab Enterprise notebook.
Learn how and when Gemini for Google Cloud uses your data .
This document is intended for data analysts, data scientists, and data developers who work with Colab Enterprise. It assumes you have knowledge of how to write code in a notebook environment.
Overview
Gemini in Colab Enterprise can help you explain code cells in a Colab Enterprise notebook. You might want to do this when you're working with someone else's notebook and want to get a quick understanding of what the code does. Or you might need to remind yourself how parts of your notebook work after a long period of time without working on it.
After you get an explanation of a code cell, you can browse any included code snippets and review the sources. You can also use the Explain codechat dialog to discuss the code and ask follow-up questions. For more details, see Explain a code cell .
Before you begin
- Ensure that Gemini in Colab Enterprise is set up for your Google Cloud user account and project.
- Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
