    I am using WSL, and when running some Python code with OpenCV that needs to open a different window, it throws an error. This is the code:

    import cv2 as cv

    image = cv.imread("images/pic.jpg")
    cv.imshow(0)
    cv.waitKey(0)


    And this is the error I get

    qt.qpa.xcb: could not connect to display
    qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/user/.local/lib/python3.8/site-packages/cv2/qt/plugins" even though it was found.
    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this
    problem.

    Available platform plugins are: xcb.

    Aborted (core dumped)
