I am currently learning machine learning and am doing the project on object detection.
My problem is that the put_text() isnt working properly in my for loop. Here is my code:
‘

classIds, confs, bbox = net.detect(img, confThreshold=0.5) 

if len(classIds) != 0:
    for classId, confidence, box in zip(classIds.flatten(), confs.flatten(), bbox):
        cv2.rectangle(img, box, (255, 0, 0), thickness=2)
        cv2.putText(img, classNames[classId-1].upper(), (box[0]+10, box[1]+30),
                    cv2.FONT_HERSHEY_COMPLEX, 1, (255, 0, 0), 2)

But here is what I got:
‘

File "C:UsersUserprojectsopencvObjectDetector.py", line 31,            
     in <module>
cv2.putText(img, classNames[classId-1].upper(), (box[0]+10, box[1]+30),
                 ~~~~~~~~~~^^^^^^^^^^^
IndexError: list index out of range

‘

I was expecting it to show an window with the camera and a box around it that specifys the objects name, but it just showed the error. How do I resolve this?
