Python error numpy.int32 object is not iterable [duplicate]

Question

I have a below python code which detect person in frame. Once detected, it get the bounding box of the person which is person_box. From person_box I can get the startX, startY and width height of the bounding box. But in below code, in for loop, I am getting error as numpy.int32 object is not iterable

person_box = person_detections[0, 0, i, 3:7] * np.array([W, H, W, H])
person_box = person_box.astype(int)
print(person_box)
(startX, startY, endX, endY) = person_box.astype("int")
width = endX - startX
height = endY - startY

for (startX, startY, width, height) in person_box:
    person_box = np.array([startX, startY, startX + width, startY + height])

output

[159 156 451 431]

I am not able to understand the error much as I am not much experienced with numpy arrays. Please help. Thanks.

for loop will iterate person_box and pass parameter by parameter. You are trying to split the parameter and assign to startX, startY, width, height in for (startX, startY, width, height) in person_box: you can just try:

person_box = np.array([person_box [0], person_box[1] , person_box[0] + person_box[2] , person_box[1] + person_box[3] ])

or

startX = person_box[0]
startY = person_box[1]
width = person_box[2]
height = person_box[3]
person_box = np.array([startX, startY, startX + width, startY + height])
