v8.3.176 - `ultralytics 8.3.176` Comet integration fix for YOLO Detect and OBB models (#21613)

on Python PyPI

🌟 Summary

Ultralytics 8.3.176 improves experiment tracking with Comet ML, streamlines YOLOE exports, and refactors tracking internals for cleaner, more flexible pipelines—plus a new CoreML video to speed up Apple deployments. 🚀📊

📊 Key Changes

• Comet ML integration (priority)
  • Automatically logs results.csv and args.yaml at the end of training for Detect and OBB (oriented bounding box) models. 📝
  • Adds helpers to log assets and tables; improves plot logging for detection/OBB metrics; clarifies type hints.
• YOLOE export and class-handling
  • Fuses YOLOE prompt embeddings during export only (not during generic fuse), improving compatibility. 🧩
  • Allows setting new classes even after fusion for YOLOE models (removed previous restriction).
• Trackers cleanup
  • BOT-SORT and BYTETracker now use a unified Results object (instead of separate arrays) to initialize and update tracks. 🔄
  • Reduces duplicate code and improves consistency; no changes to typical user-facing APIs.
• Docs enhancement
  • Added a YouTube tutorial to the CoreML guide showing how to export YOLO11 for faster Apple device inference. 🎥📱

🎯 Purpose & Impact

• Better experiment traceability
  • Key artifacts (metrics table, run config) are saved automatically to Comet ML, making runs easier to analyze, reproduce, and share. ✅
• Smoother YOLOE deployment
  • Export-time fusion reduces errors and increases format compatibility; post-fusion class setting makes model customization simpler. ⚙️
• More maintainable tracking
  • Unified result handling simplifies extensions and future features; developers benefit from cleaner, consistent internals. 🧼
• Faster Apple workflows
  • The new CoreML video helps users export YOLO11 for up to 2x faster inference on iOS and macOS, improving real-world deployment speed. ⚡

No expected breaking changes for most users. 🎉
