🌟 Summary

Enhanced logging intervals for Comet.ml in Ultralytics YOLOv5.

📊 Key Changes

• Adjusted the logging frequency of predictions to Comet.ml when using YOLOv5.

🎯 Purpose & Impact

• 🛠 Fixes an issue with setting the interval for logging predictions to Comet.ml to ensure more consistent behavior.
• 🚀 Users with shorter training runs (less than 10 epochs) will now get prediction logs every epoch, enhancing the monitoring and evaluation experience.
• 📈 This leads to better insight and tracking for small-scale experiments, potentially improving model development and debugging processes.

@glenn-jocher Added the link to the Comet tutorial to the main README. Also found a bug this morning regarding bbox_interval and division by zero errors in the Comet Logger. So I made a fix for that as well.
