Question

I was trying to read a threshold image but I have a problem...

from cv2 import cv2
import numpy as np

img = cv2.imread('page.jpeg')

color = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
thresh = cv2.threshold(color, 10, 255, cv2.THRESH_BINARY)

cv2.imshow('thresh', thresh)
cv2.imshow('picture', color)
cv2.waitKey(0)
cv2.destroyAllWindows()
