Python Object detection screen not responding

[sanadatari]

I have the python code here
import cv2
import matplotlib.pyplot as plt
import cvlib as cv
import urllib.request
import numpy as np
from cvlib.object_detection import draw_bbox
import concurrent.futures

url='http://192.168.43.73/cam-hi.jpg'
im=None

def run1():
cv2.namedWindow("live transmission", cv2.WINDOW_AUTOSIZE)
while True:
img_resp=urllib.request.urlopen(url)
imgnp=np.array(bytearray(img_resp.read()),dtype=np.uint8)
im = cv2.imdecode(imgnp,-1)

    cv2.imshow('live transmission',im)
    key=cv2.waitKey(5)
    if key==ord('q'):
        break
        
cv2.destroyAllWindows()

def run2():
cv2.namedWindow("detection", cv2.WINDOW_AUTOSIZE)
while True:
img_resp=urllib.request.urlopen(url)
imgnp=np.array(bytearray(img_resp.read()),dtype=np.uint8)
im = cv2.imdecode(imgnp,-1)

    bbox, label, conf = cv.detect_common_objects(im)
    im = draw_bbox(im, bbox, label, conf)

    cv2.imshow('detection',im)
    key=cv2.waitKey(5)
    if key==ord('q'):
        break
        
cv2.destroyAllWindows()

if name == 'main':
print("started")
with concurrent.futures.ProcessPoolExecutor() as executer:
f1= executer.submit(run1)
f2= executer.submit(run2)
i am using python spyder how ever there are two screens the live one totally works fine while the detection objective one doesnt work it says not responding any idea?

I think it goes somewhere wrong before the imshow() call. What does cv.detect_common_objects() return? Are the variables set or null? Verify that img_resp is not empty

There are different ways to do object detection, you could try different methods
