don't show lables on the detected objects

[nikinbaidar]

        v = Visualizer(self.img[:, :, ::-1], metadata=metadata,
                       scale=0.5, instance_mode=ColorMode.IMAGE_BW)
        instances = instances.to("cpu")
        out = v.draw_instance_predictions(instances)

This displays the label and the probability of the detected object, how can I only show the bounding boxes and drop the labels/probability?
