Hello @Sanmilee, 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!

Summary of Changes

This pull request addresses a NoneType object error in the use_case_company_news_and_insights.ipynb notebook. The primary change involves adding a try-except block to handle potential AttributeError exceptions that can occur when accessing the function_call.name attribute of a Gemini API response. Additionally, the PR includes updates to execution counts, adds the author to the notebook, and incorporates a helper function to extract function calls from the API response. The prompt given to the LLM is also updated to include a request for a concise, high-level summary.

Highlights

• Error Handling: Implements a try-except block to gracefully handle AttributeError exceptions when processing Gemini API responses, preventing the notebook from crashing when a function call is not present.
• Function Call Extraction: Adds a helper function extract_function_calls to parse and extract function calls from a Gemini GenerationResponse, facilitating easier access to function names and arguments.
• Prompt Update: Modifies the prompt sent to the Gemini API to explicitly request a concise, high-level summary, improving the quality of the generated responses.
• Author Addition: Adds the author, Ariyo Oluwasanmi, to the notebook's author list.

Changelog

• gemini/function-calling/use_case_company_news_and_insights.ipynb
  • Added Ariyo Oluwasanmi to the author list.
  • Set initial execution count to null.
  • Updated execution counts for various code cells.
  • Imported GenerationResponse from vertexai.generative_models.
  • Added a helper function extract_function_calls to extract function calls from the API response.
  • Added a try-except block to handle AttributeError when extracting function call names.
  • Updated the prompt to request a concise, high-level summary.
  • Modified the API key to be commented out by default.

Code Review

The pull request aims to fix a NoneType object error in the use_case_company_news_and_insights.ipynb notebook. The changes include adding a new author, updating execution counts, importing GenerationResponse, commenting out the API key, modifying the send_chat_message function to handle multiple function calls, and updating the outputs of several code cells. Overall, the changes seem to address the error and improve the functionality of the notebook.

Summary of Findings

• Error Handling in send_chat_message: The send_chat_message function now uses a broad AttributeError exception to handle cases where a natural language response is received instead of a function call. While this addresses the immediate error, it might mask other potential AttributeError exceptions that could occur within the try block. A more specific exception handling approach would be beneficial.
• Inconsistent Output Formatting: The output formatting in the notebook is inconsistent. Some cells display '#### Predicted function name' while others display '#### Function Extraction' for the same purpose. Standardizing the output format would improve readability.
• API Key Security: The API key is commented out in the notebook. While this prevents accidental exposure, it also means the notebook won't function correctly without the user providing their own key. Consider providing instructions on how to obtain and set the API key.

Merge Readiness

The pull request addresses the reported error and introduces some improvements to the notebook. However, the broad exception handling in send_chat_message and the inconsistent output formatting should be addressed before merging. Additionally, clear instructions on setting up the API key are necessary for the notebook to be functional. I am unable to approve this pull request, and recommend that others review and approve this code before merging.
