📋 Summary

RF-DETR 1.8.1 is a patch release with seven bug fixes and three quality-of-life improvements. The highlights: two compatibility crashes are fixed — one hitting environments that have tensorflow alongside NumPy 2.0, another hitting Albumentations 2.x users — and per-epoch metric tables show up again during training instead of being hidden behind the progress bar. No breaking changes, and nothing to migrate from v1.8.0.

🗒️ Notable changes

🌱 Changed

  • pathlib.Path accepted for path parameters — path fields on TrainConfig and related config classes now accept pathlib.Path objects directly. (#1124)
  • Horizontal flip disabled for keypoint training — flip augmentation is turned off for keypoint training for now, since it could produce incorrect labels without keypoint flip-pair reordering. (#1122)
  • Training metric plots — improved plotting with optional error bands, AP@0.75 grouping, and configurable AP metric groups. (#1122)

🔧 Fixed

  • TensorBoard + NumPy 2.0 crash — training falls back to CSV logging with a warning instead of crashing when TensorBoard can't be imported. (#1123)
  • Albumentations 2.x compatibility — fixed a crash in horizontal-flip detection when using Albumentations 2.x. (#1126)
  • Metric tables hidden by the progress bar — per-epoch metric tables now render correctly alongside the live training progress bar. (#1128)
  • Keypoint checkpoint selection — best-checkpoint selection for keypoint models is now smoothed, avoiding spurious switches on noisy OKS metrics; smoothing also survives a training resume. (#1122)
  • Keypoint encoder evaluation — fixed query routing in eval mode so keypoint predictions are computed correctly. (#1135)
  • Group DETR train-time evaluation — fixed a crash during train-time evaluation in Group DETR mode. (#1122)
  • DINOv2 backbone config compatibility — internal call sites updated from deprecated config.use_return_dict to config.return_dict. (#1135)
