ultralytics.models.yolo.obb.train.OBBTrainer

Basi: DetectionTrainer

Una classe che estende la classe DetectionTrainer per l'addestramento basato su un modello Oriented Bounding Box (OBB).

Esempio
from ultralytics.models.yolo.obb import OBBTrainer

args = dict(model='yolov8n-obb.pt', data='dota8.yaml', epochs=3)
trainer = OBBTrainer(overrides=args)
trainer.train()
