The last dimension of y_true has 6 values.

• the first four value is the box coordinates, like xywh or xyxy
• the 5th value is the confidence of the detection box, for y_true it's 1
• the 6th value is the classification label, in coco dataset it has 80 classes. In the loss function, this is expand into one-hot further
