RuntimeError: cannot perform reduction function max on tensor with no elements because the operation does not have an identity

[Syazaniwhd]

I am running the algorithm on a Mac OS and this is the error I get when I run the detect.py file

run code:
python detect.py --weights yolov5s.pt --source data/images/carpark1.jpg

error output:
Namespace(agnostic_nms=False, augment=False, classes=None, conf_thres=0.4, device='', img_size=1024, iou_thres=0.5, output='inference/output', save_txt=False, source='data/images/carpark1.jpg', update=False, view_img=False, weights=['yolov5s.pt'])
