ultralytics.models.yolo.obb.train.OBBTrainer 

OBBTrainer(cfg=DEFAULT_CFG, overrides=None, _callbacks=None)

Bases: DetectionTrainer

A class extending the DetectionTrainer class for training based on an Oriented Bounding Box (OBB) model.

Example 
from ultralytics.models.yolo.obb import OBBTrainer

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

    """Initialize a OBBTrainer object with given arguments."""
    if overrides is None:
        overrides = {}
    overrides["task"] = "obb"
    super().__init__(cfg, overrides, _callbacks)

get_model 

get_model(cfg=None, weights=None, verbose=True)
