python AttributeError opencv

Question

i am new to opencv and am trying to simply display an image, however with every cv2 function I get the same error, (AttributeError)

I have already installed pip install opencv-contrib-python witch was suggested to fix this problem but changed nothing,

import cv2
img = cv2.imread ("C:\\Users\\Astroid\\Desktop\\desktop backround pics\\560736.jpg", 1)
print(img)
cv2.imshow("560736",img)
cv2.WaitKey(2000)
cv2.DestroyAllWindows()

full error is.

Traceback (most recent call last): File "C:/Users/Astroid/.PyCharmCE2019.1/config/scratches/scratch.py", line 6, in cv2.WaitKey(20000) AttributeError: module 'cv2.cv2' has no attribute 'WaitKey'

Use lowercase for the method: [docs]

retval = cv.waitKey([, delay])

thx, that worked for waitkey however i sayed that the same AttributeError was happening to all the cv2 functions, after i implemented your line of code it desplaye the image however the program ended in Traceback (most recent call last): File "C:/Users/Astroid/.PyCharmCE2019.1/config/scratches/scratch.py", line 7, in <module> cv2.DestroyAllWindows() AttributeError: module 'cv2.cv2' has no attribute 'DestroyAllWindows' and when i implemented this line in reasized = cv2.reasize(img, (800,600)) the same happend

The naming convention across cv2 is lowercase for first letter then camel case so it should be destroyAllWindows()
