[Python] I'm trying to do a Color Detector in openCV but it just isn't working

So I am watching this tutorial, and following everything, and I'm running into this one issue. For some reason I'm getting an error in inRange saying that overload resolution failed, upperb is not a numerical tuple. Expected Ptr for argurment 'upperb'. I don't understand why lowerb works but upperb doesn't

colorSorter.py

import cv2 import numpy as np

from util import get_limits

yellow = [0, 255, 255] #Yellow in RGB colorspace cap = cv2.VideoCapture(0)

while True: ret, frame = cap.read()

hsvImage = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV)

lowerb , upperb = get_limits(color=yellow)


mask = cv2.inRange(hsvImage, lowerb, upperb)

cv2.imshow('frame', mask)

if cv2.waitKey(1) & 0xFF == ord('q'):
break


cap.release()

cv2.destroyAllWindows()

util.py

import numpy as np import cv2

def get_limits(color): c = np.uint8([[color]]) hsvC = cv2.cvtColor(c, cv2.COLOR_BGR2HSV)

lowerb = hsvC[0][0][0] - 10, 100, 100
upperb = hsvC[0][0][0] + 10, 255, 255

lowerb = np.array(lowerb,dtype=np.uint8)
upperb = np.array(upperb,dtype=np.uint8)

return lowerb, upperb


I was expecting my window to pop up in a mask that will be all black expect if yellow is detected on the camera
