    Usage examples for running YOLOv8:

    1. Install the ultralytics package:

        pip install ultralytics

    2. Use the Python SDK:

        from ultralytics import YOLO

        # Load a model
        model = YOLO('yolov8n.yaml')  # build a new model from scratch
        model = YOLO("yolov8n.pt")  # load a pretrained model (recommended for training)

        # Use the model
        results = model.train(data="coco128.yaml", epochs=3)  # train the model
        results = model.val()  # evaluate model performance on the validation set
        results = model('https://ultralytics.com/images/bus.jpg')  # predict on an image
        success = model.export(format='onnx')  # export the model to ONNX format

    3. Use the command line interface (CLI):

        YOLOv8 'yolo' CLI commands use the following syntax:

            yolo TASK MODE ARGS

            Where   TASK (optional) is one of [detect, segment, classify]
                    MODE (required) is one of [train, val, predict, export]
                    ARGS (optional) are any number of custom 'arg=value' pairs like 'imgsz=320' that override defaults.
                        See all ARGS at https://docs.ultralytics.com/usage/cfg or with 'yolo cfg'

        - Train a detection model for 10 epochs with an initial learning_rate of 0.01
            yolo detect train data=coco128.yaml model=yolov8n.pt epochs=10 lr0=0.01

        - Predict a YouTube video using a pretrained segmentation model at image size 320:
            yolo segment predict model=yolov8n-seg.pt source='https://youtu.be/LNwODJXcvt4' imgsz=320

        - Val a pretrained detection model at batch-size 1 and image size 640:
            yolo detect val model=yolov8n.pt data=coco128.yaml batch=1 imgsz=640

        - Export a YOLOv8n classification model to ONNX format at image size 224 by 128 (no TASK required)
            yolo export model=yolov8n-cls.pt format=onnx imgsz=224,128

        - Run special commands:
            yolo help
            yolo checks
            yolo version
            yolo settings
            yolo copy-cfg
