Hi,

I followed installation instructions for Jetson Nano here

But instead of getting default GUI, I am getting following screens on running python3 depthai_demo.py

    Hi AnshumanFauzdar
    Perhaps the CV is selected as a default driver for GUI or the QT installation is faulty.
    Try this:
    python3 depthai_demo.py -gt qt

    I know cv is used by default for RPI due to it's slow processing speed; but it should be fine for jetson.

    Hope it helps,
    Jaka

        jakaskerl I tried the command, now it gives following error:

        Traceback (most recent call last):

        File "depthai_demo.py", line 1059, in <module>

        raise RuntimeError("QT backend is not available, run the script with --guiType \"cv\" to use OpenCV backend")

        RuntimeError: QT backend is not available, run the script with --guiType "cv" to use OpenCV backend

        Sentry is attempting to send 2 pending error messages

        Waiting up to 2 seconds

        Press Ctrl-C to quit

        In hardware side, there is a click sound [very faint but audible] when I start depathai_demo.py, is it normal or should I return to the vendor for replacement?

        I am missing some quick start guide which is available? I have also purchased OAK-D CM4 module and also facing some problems in that module. Is there any FAQ available or should I start discussion here only?

            jakaskerl Hi, I tried the depthai-viewer, its working with some glitches in Windows but on jetson nano I am getting following error while installation, there is no pre-built whl for this installation I will wait for it officially otherwise compiling rust and python will be a long task :

            Defaulting to user installation because normal site-packages is not writeable

            ERROR: Could not find a version that satisfies the requirement depthai-viewer (from versions: none)
