We have an oak-d-cm4-poe device that we have been using for several months with no issue. Last week we stopped being able to record on it. We tested it with the depthai_demo.py code to make sure it wasn't an issue with our custom codebase, and the demo code wasn't working either. We get the following error message:

pi@oak3:~/depthai $ python depthai_demo.py

Not sure what's causing this. I confirmed x forwarding is working ok on the computer I am using to ssh into the device as I did the exact same procedure sshing into another of our oak-d-cm4-poe devices and everything worked correctly without issue.

If anyone has run into something similar or has an idea of what could be causing the issue please let me know 🙂

    Hi jack-t
    Please use the latest depthai version you can.

    Thanks,
    Jaka

      I tried upgrading the depthai version using pip, however when I run depthai_demo.py it then gives me an error and instructs me to install the correct requirements using install_requirements.py. When I do this it just reinstalls the 2.17.3.0 version.

      But also I doubt that this is the issue as we were previously using this version for months without issue and are still using this version without issue on several other devices.

        Hi jack-t,
        You would have to update to the latest depthai repository commit (https://github.com/luxonis/depthai).
        Alternatively, you can run the depthai_demo.py with --skipVersionCheck flag, but since you are on a much older version, it might not work properly.

        Sometimes, running experiments with different versions/dependencies will bug the host, which would cause the issues you are experiencing. You could have unknowingly changed something that causes the said error.

        Let me know if it still doesn't work.

        Thanks,
        Jaka

          I updated the depthai package as you suggested (with a git pull) and it looked to update correctly now. When I ran the depthai_demo.py I got a very similar error message as before, new error message shown below.

          pi@oak3:~/depthai $ python depthai_demo.py

              Second command - it produces the very long output shown below, then hangs and I have to exit it with ctrl-c:

                jack-t terminal output looks good. Did you install the requirements?

                sudo wget -qO- https://docs.luxonis.com/install_dependencies.sh | bash

                  Just ran that and it did update some stuff. However, when I run depthai_demo.py it still errors. The new error message is similar to before but a little different now. I have shown the new error message below. It displays this error, then the execution hangs. The demo window pops up, but the video feed is empty, it just says "starting demo…".

                  pi@oak3:~/depthai $ python depthai_demo.py
