python error

I don't change any code,just run :yolov8Det = trainYOLOv8ObjectDetector('data.yaml','yolov8n.pt', ImageSize=[720 720 3], MaxEpochs=10);  

There is no module or function named 'trainYOLOv8Wrapper'.

Error trainYOLOv8ObjectDetector (line 88)
pythonObject = py.trainYOLOv8Wrapper.yolov8TrainerClass(py.str(baseModel),py.int(options. ImageSize(1,1)));
