I am using the following code:
import cv2
import numpy as np
import pyautogui
import sys
img = pyautogui.screenshot()
cv2.imshow('image',img)
When I run this, it tells me
mat is not a numpy array, neither a scalar
I have tried to use different functions from opencv and it seems they all return the same. What do I need to do in order to take a screenshot then work with it in Open CV?
