i have python code like this
import cv2
import numpy
img = np.zeros([512,512,1], dtype=np.uint8)
img.fill(255)
cv2.imshow('test', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
it should be show blank image with white background. i can run this on terminal, but when im running this on visual studio code, its shows
: cannot connect to X server
previously i can do this on my visual studio code and now i cannot do this again. my settings in linux are :
- Ubuntu 20.04
- Python 3.8
- Opencv 4
i know there are many question about this issue, i already try
- xhost local:root
- import os os.environ['DISPLAY'] = ':0'
but nothing can solved my issue. i also re-install opencv and visual studio code. any help would appreciate. thank you very much
