Unspecified error and the function is not implemented in opencv

Question

python duke.py

Traceback (most recent call last): File "duke.py", line 5, in cv2.imshow('ktm',img)

cv2.error: OpenCV(3.4.2) /opt/conda/conda-bld/opencv-suite_1535678557175/work/modules/highgui/src/window.cpp:632: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

here is my code

import cv2
img = cv2.imread('Downloads/404615.jpg',1)

while True:

    cv2.imshow('ktm',img)

    if cv2.waitkey(1) & 0*FF == 27:
        break

cv2.destroyAllWindows()
