S )SegmentationTrainerar  
    A class extending the DetectionTrainer class for training based on a segmentation model.

    Example:
        ```python
        from ultralytics.models.yolo.segment import SegmentationTrainer

        args = dict(model="yolov8n-seg.pt", data="coco8-seg.yaml", epochs=3)
        trainer = SegmentationTrainer(overrides=args)
        trainer.train()
        ```
