      Hi,

      I installed opencv for Intel edison from Alext"s repository.
      Now I'm trying to capture image from webcam using opencv but it gives the following error:-

       

      Error:-

      (frame:2379): Gtk-WARNING **: cannot open display:

       

       

      My code:-

       

      import numpy as np

      import cv2

       

      cap = cv2.VideoCapture(0)

      while(True):

          # Capture frame-by-frame

          ret, frame = cap.read()

          # Display the resulting frame

          cv2.imshow('frame',frame)

          if cv2.waitKey(1) & 0xFF == ord('q'):

              break

      # When everything done, release the capture

      cap.release()

      cv2.destroyAllWindows()

       

       

      how to solve this ?
