🌟 Summary

Implementation of a new initialization file for model management in the Ultralytics YOLOv5 repository.

📊 Key Changes

• A new __init__.py file has been added to the models directory.

🎯 Purpose & Impact

• The new __init__.py file ensures that Python treats the directories containing it as packages. This facilitates the import of modules from the models directory elsewhere in the project.
• The change potentially improves modularity and organization of the codebase, making it easier for developers to work with the model components of YOLOv5.
• For users, this change is mostly behind the scenes but can lead to smoother installation and usage of the YOLOv5 models as dependencies become more clearly defined.
