🌟 Summary

Enhanced class name retrieval in Ultralytics models for more flexibility.

📊 Key Changes

• Modified how class names are obtained from models: now supports an additional method via self.predictor.
• Code structure around retrieving model names has been refined for better clarity and maintainability.

🎯 Purpose & Impact

• Purpose: The change aims to provide a more robust and flexible way of accessing class names in models, particularly when the direct names attribute isn't available.
• Impact: Users and developers can now expect more consistent behavior when working with different Ultralytics models, potentially improving user experience and compatibility with a broader range of models. 🚀
