🌟 Summary

Improved error handling and data processing in anchor optimization for YOLOv5.

📊 Key Changes

• Introduced a TryExcept decorator for cleaner error handling.
• Adjusted anchor checking to use the new decorator, removing explicit try-except blocks.
• Changed how small object warnings are output and how relevant data is filtered.
• Ensured consistent data type (float32) for anchor processing results.

🎯 Purpose & Impact

• 🚀 Enhanced Readability: Refactoring for better error management makes the code more readable and maintainable.
• 🛠️ Robustness: Errors during anchor checking will now be handled more gracefully, reducing potential crashes or hangs.
• 🎛️ Data Consistency: Data type standardization helps prevent type mismatch errors and ensures reliable performance across different systems.
• 🚨 Clear Warnings: Users will get clearer information about potential issues with their data, specifically extremely small objects which might affect model accuracy.
