Ultralytics YOLO

🌟 Summary

The Ultralytics v8.3.90 release introduces several key updates, including a fix for memory usage calculations on Apple MPS devices, documentation enhancements, and architectural optimizations across YOLO models. 🚀

📊 Key Changes

• MPS Memory Fix: Updated memory usage calculation for Metal Performance Shaders (MPS) devices to improve accuracy using psutil.virtual_memory().percent.
• YOLO Model Optimizations: Reduced the number of layers across YOLO11, YOLOv8, and YOLOv9 models for improved efficiency without compromising performance.
• Documentation Improvements: Enhanced clarity, formatting, and consistency across multiple files, including detailed descriptions for methods and parameters.
• Logging Enhancements: Improved logging behavior for better user control and debugging.
• C++ Example Fix: Resolved input image dimension handling in YOLOv8 C++ inference code.
• Default Solution Handling: Added fallback to "count" solution when no solution name is provided in YOLO commands.

🎯 Purpose & Impact

• Enhanced User Experience:
  • Apple MPS users benefit from more accurate memory tracking, optimizing resource management during training or inference. 🍎
  • Clearer documentation and improved logging make the platform more user-friendly and easier to debug.
• Performance Boost:
  • YOLO model optimizations lead to faster inference times and reduced computational overhead, enhancing efficiency for various tasks. ⚡
• Developer Convenience:
  • Fixes in C++ examples and default solution handling streamline workflows for developers.

This release ensures better compatibility, performance, and usability for both developers and end-users. 🌟
