ultralytics 8.4.172

v8.4.172 - `ultralytics 8.4.172` Add rotation-aligned OBB crops to save_crop (#26486)

on Python PyPI

🌟 Summary

v8.4.172 makes oriented-box cropping work as expected and improves reliability across model training, export, dataset handling, and deployment.

📊 Key Changes

• Rotation-aligned OBB crops: save_crop=True and ObjectCropper now save crops upright and aligned to each oriented bounding box. Areas extending beyond the image are filled with black.
• Model correctness fixes: AIFI positional embeddings now match non-square feature maps, and RT-DETR computes matching costs in float32 to avoid AMP precision errors affecting training assignments.
• More reliable training and resume: NaN recovery now correctly restarts the recovered epoch, while resumed runs preserve the selected optimizer and early-stopping progress.
• Improved dataset and export handling: Corrupted dataset caches trigger a rescan; classification datasets recognize more supported image formats; and static INT8 exports can calibrate even when the dataset is smaller than the requested batch.
• Broader Python support: Python 3.14 is added to package support and several Docker and export environments. The Python export image remains on Python 3.13 for dependencies that do not yet support 3.14.
• Platform documentation refreshed: Docs now describe current Platform behavior and APIs, including Agents management, dataset version comparisons, and direct LabelMe imports.

🎯 Purpose & Impact

• OBB users can now get useful, tightly aligned crops instead of no crops or axis-aligned approximations.
• Training and validation should be more dependable, particularly when using AMP, recovering from NaNs, or resuming an interrupted run.
• Dataset and export workflows are more resilient to damaged caches, varied image formats, and small calibration datasets.
• Updated Python support and clearer Platform documentation make it easier to choose compatible environments and follow current workflows.
