The following python code fails but should display an image (obviously need to change paths to suite to repro). This is causing me a lot of issues with samples I'm trying to run.
import cv2
image = cv2.imread("image1.jpg")
cv2.imshow("test", image)
cv3.waitKey(0)
CV2 is installed and will read the image data, but the show method fails, with the following error:
OpenCV(3.4.2) /tmp/build/80754af9/opencv-suite_1535558553474/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'

cv2.imshow("test", image)
> Btw this form is terrible - I couldn't copy paste code in, I had to rewrite it.

There are two DSVM images on marketplace:- Please use the below links to create the same.
Edited:
OpenCV library is supported for Ubuntu Server 18.04 DSVM. Once the image is loaded using cv2, Instead of cv2.imshow() use the inline script to show the image. I have validated this on the VM:
import cv2
import numpy as np
from matplotlib import pyplot as plt
img = cv2.imread('path_to_image.jpg',cv2.IMREAD_GRAYSCALE)
plt.imshow(img, cmap = 'gray', interpolation = 'bicubic')
plt.xticks([]), plt.yticks([]) # to hide tick values on X and Y axis
plt.plot([200,300,400],[100,200,300],'c', linewidth=5)
plt.show()

Well that's a long answer pity it ignored my question completely!
The sample you referenced was from 3 years ago, so it has little relevance to prove that it would work on the latest DSVM. As I stated (ok I had a slight typo but should still have been clear) I am already using the DSVM Ubuntu 18.04 image which was setup a few weeks ago. The sample code I provided DOES NOT WORK, however it SHOULD work.
Its clear that the OpenCV library has not been installed/configured correctly on this image. Can you please address my issue.
Note in my sample code where you see
&#34;its a quote, seems it was converted for some reason.

Hi,
OpenCV library is supported for Ubuntu Server 18.04 DSVM.
Once the image is loaded using cv2, Instead of cv2.imshow() use the inline script to show the image. I have validated this on the VM:

from matplotlib import pyplot as plt
img = cv2.imread('path_to_image.jpg',cv2.IMREAD_GRAYSCALE)

plt.xticks([]), plt.yticks([]) # to hide tick values on X and Y axis
plt.plot([200,300,400],[100,200,300],'c', linewidth=5)
plt.show()
