Let's visualize the predictions:

from PIL import ImageDraw
draw = ImageDraw.Draw(image)
for prediction in predictions:
     box = prediction["box"]
     label = prediction["label"]
     score = prediction["score"]

     xmin, ymin, xmax, ymax = box.values()
     draw.rectangle((xmin, ymin, xmax, ymax), outline="red", width=1)
     draw.text((xmin, ymin), f"{label}: {round(score,2)}", fill="white")
