Summary of Changes

Hello @Jintao-Huang, 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 implements a crucial validation step within the test_convert_precision function to ensure its proper application. It specifically prevents the test from executing on models configured for FP8 precision, which currently do not support this type of precision conversion testing. This change enhances the robustness of the testing suite by guiding users away from unsupported configurations and preventing potential errors or misleading test results.

Highlights

• FP8 Model Compatibility: Added a check within the test_convert_precision function to prevent it from running on models configured with FP8 (8-bit floating point) precision.
• Error Handling: Introduced a ValueError that is raised when test_convert_precision is invoked with an FP8 model, providing a clear message and suggesting to disable the test via --test_convert_precision false.

Code Review

This pull request introduces a check in test_convert_precision to prevent it from running on fp8 models, as this scenario is currently unsupported. The change is straightforward and adds a ValueError with a clear message for the user, guiding them to disable the test via a command-line argument. This is a good defensive programming practice that improves user experience by failing early with an informative error message instead of a potentially obscure one later on. The implementation is correct and well-placed within the function.
