Summary of Changes

Hello @ST-XX, 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 enhances the fastdeploy utility module by integrating NVIDIA Tools Extension (NVTX) profiling capabilities. It provides convenient decorators to mark code sections for performance analysis, allowing developers to gain deeper insights into the execution flow and identify performance bottlenecks within functions and class methods.

Highlights

• NVTX Function Annotation: Introduced a new decorator, nvtx_annotate, which allows for easy application of NVTX range annotations to individual functions, enabling detailed performance profiling.
• Automatic Class Method Annotation: Added nvtx_class_annotate, a class decorator that automatically applies NVTX annotations to all public methods within a class, streamlining the profiling setup for complex objects.

Code Review

This pull request introduces utility decorators for adding NVTX annotations, which is useful for performance profiling. The implementation is straightforward, but it could be made more robust by handling cases where the nvtx package is not installed. I've suggested a refactoring to gracefully degrade the functionality when nvtx is unavailable, which improves the utility's usability in different environments. I've also improved the docstrings for better clarity.

Code Review

This pull request introduces two utility decorators, nvtx_annotate and nvtx_class_annotate, to add NVTX profiling annotations. This is a useful addition for performance analysis.

My review includes two main suggestions for improvement:

1. Make nvtx_annotate more robust by handling cases where the nvtx library is not installed. This would make it a no-op instead of raising an ImportError.
2. Correct the method detection logic in nvtx_class_annotate to specifically target functions and methods, avoiding the incorrect decoration of nested classes.

These changes will improve the robustness and correctness of the new profiling utilities.
