However, note that the YOLOv8 model usually outputs raw prediction tensors. So, you'll need to apply specific post-processing steps such as applying the sigmoid function, calculating and applying anchor grids, and non-max suppression to extract meaningful predictions (bounding boxes, class labels,...
