Summary of Changes

Hello @gericdong, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the notebook_template.ipynb to enhance its readability and maintainability. The primary goal is to streamline the notebook's structure by centralizing all import statements and simplifying section headings. This change makes the template cleaner and more intuitive for users, improving the overall developer experience when starting new projects based on this template.

Highlights

• Centralized Imports: All necessary library imports (os, sys, vertexai, google.colab.auth) have been consolidated into a single, dedicated 'Import libraries' cell at the beginning of the notebook template.
• Removed Redundant Imports: Duplicate import statements have been removed from subsequent cells, such as the authentication, project ID definition, and Vertex AI initialization sections, leading to cleaner code blocks.
• Simplified Headings: Markdown headings have been made more concise, specifically 'Install Vertex AI SDK for Python and other required packages' was shortened to 'Install required packages' and 'Initialize Vertex AI SDK for Python' to 'Initialize Vertex AI SDK'.

Code Review

This pull request refactors the notebook template by moving all Python imports into a dedicated cell at the beginning. This is a great improvement for code organization and readability, and it aligns with the repository's authoring guidelines. I have one minor suggestion to sort the imports alphabetically to fully adhere to the specified Python style guide.
