detections[0, i, j, 1:] gives number above 1

I used the test script for testing the net.
before I multiply the coordinates by scale

pt = (detections[0, i, j, 1:]).cpu().numpy()
coords = (pt[0], pt[1], pt[2], pt[3])

I get numbers above 1
for example: (0.2503756, 1.0008582, 0.2537056, 1.0039957)

What could be the cause of this problem?
