Hello, When I print out the box_confidence tensor , I see the following values, shouldnt these be between 0 and 1? After doing the required multiplication I get very high scores and ther filter returns true for everything

tf.Tensor(
[[[[ 0.885695 ]
[ 1.6324562 ]
[-1.0968447 ]
[-1.3350451 ]
[ 1.3657959 ]]

[[-6.310956 ]
[-0.54382193]
[-0.24732351]
[-3.580883 ]
[-3.31002 ]]

[[ 0.54773545]
[ 4.758901 ]
[ 1.6720673 ]
[ 4.213396 ]
[-1.2036383 ]]

Please ignore the outputs of test code. What matters is the output of the real prediction by running this line:

out_scores, out_boxes, out_classes = predict("test.jpg")

You can check the all values are indeed in [0, 1] inside yolo_filter_boxes with

print(((0 <= box_confidence) & (box_confidence <= 1)).numpy().all())
