🛠️ PR Summary

_{Made with ❤️ by Ultralytics Actions}

🌟 Summary

Refactoring of logger setup for cleaner code in the YOLOv5 repository.

📊 Key Changes

• Removed the redundancy of declaring a logger_name variable.
• Directly passed the logger name "yolov5" to the getLogger function.
• Retained the initialization of logging before defining the global LOGGER object.

🎯 Purpose & Impact

• 🧹 Code Streamlining: Simplifies the logging setup by eliminating an unnecessary variable assignment without altering functionality.
• 🚀 Maintainability: Enhances code maintainability by having one less variable that developers need to track.
• ✅ No Impact to Users: The update does not affect the features or output that end-users interact with; the functioning of the logger remains consistent.

@rkechols I need to revert this PR as Colab logging output is now duplicated, i.e.:
https://colab.research.google.com/github/ultralytics/yolov5/blob/master/tutorial.ipynb

Please see if you can create a fix that works correctly with Colab as well, thank you!
