In opencv 4.0.0 the below solution works:

import cv2
cv2.namedWindow("myImage", cv2.WINDOW_NORMAL)
image = cv2.imread("./image.jpg")
cv2.imshow("myImage", image)
cv2.waitKey(0)
cv2.destroyAllWindows()

You need to pass CV_WINDOW_AUTOSIZE when creating the namedWindow (or WINDOW_AUTOSIZE if you import cv2 instead of cv)

Here is an example:

cv2.namedWindow("window", cv2.WINDOW_AUTOSIZE) 
# or cv.namedWindow("window",cv.CV_WINDOW_AUTOSIZE)
cv2.imshow("window", yourimage)
