on GitHub

🌟 Summary

This release introduces a new, faster YAML utility class for more efficient and reliable configuration handling, along with documentation improvements and performance optimizations across the Ultralytics codebase. 🚀🗂️

📊 Key Changes

• Unified Fast YAML Utility: Added a new YAML class for loading, saving, and printing YAML files, replacing all previous YAML handling methods for better speed and consistency.
• Performance Boost: The new YAML class automatically uses the fastest available parser (C-based when possible) and gracefully handles encoding and edge cases.
• Scoped Imports for Faster Startup: Matplotlib and related plotting libraries are now imported only when needed, reducing initial load time and memory usage.
• Enhanced Documentation: Solution guides now clearly document new visualization options (show_conf, show_labels) and provide improved usage examples.
• Cleaner Configurations: The workspace parameter in the default config is now left blank by default, clarifying its optional nature for TensorRT exports.
• Minor Fixes: Improved file suffix checks and path handling for better robustness.

🎯 Purpose & Impact

• Faster and More Reliable YAML Handling: Users benefit from quicker configuration file operations and fewer errors related to encoding or YAML parsing.
• Smoother User Experience: Faster imports and reduced overhead, especially for users who don't need plotting features, make Ultralytics tools more responsive and lightweight.
• Easier Customization: Expanded and clearer documentation helps users take advantage of new visualization features and better understand available options.
• Reduced Confusion: Configuration files are now easier to edit and understand, especially for advanced export scenarios.
• Improved Code Maintainability: A unified approach to YAML operations simplifies future development and troubleshooting.

Overall, this update makes working with Ultralytics models and solutions faster, more robust, and more user-friendly for everyone! ✨📈
