ultralytics 8.4.98 on Python PyPI

🌟 Summary

v8.4.98 improves Hailo export compatibility for legacy YOLO checkpoints while preserving strict model-family validation. 🚀

Legacy checkpoint support for Hailo export 🛠️
Hailo exports can now identify the model family from its architecture when older checkpoints do not include the optional yaml_file metadata.
Topology-based model detection 🔍
The exporter examines backbone and head components to recognize supported YOLOv8, YOLO11, and YOLO26 checkpoints when metadata is missing.
Existing validation remains intact ✅
The detection-head checks and supported-family restrictions were preserved, preventing unsupported architectures such as YOLOv5, YOLOv10, and YOLO12 from being sent to Hailo’s Dataflow Compiler.
Patch version updated 📦
The package version was incremented from 8.4.97 to 8.4.98.

More reliable deployment of older models: Legacy trained checkpoints can now be exported to Hailo without requiring metadata that was not consistently stored in older versions.
No change to supported model scope: The update improves checkpoint recognition rather than adding unsupported model families.
Safer exports: Existing architecture validation continues to catch incompatible models before Hailo compilation, reducing confusing downstream failures.
Broad compatibility coverage: Testing confirmed that metadata-stripped YOLOv8, YOLO11, and YOLO26 checkpoints are accepted, while unsupported families are correctly rejected. 🧪
