Hi Ali ! Please make sure that you are using the original USB type -C cable from the luxonis… You may plug out the camera from the Pi and the reconnect it and run the Programme it might help as well…

      I'm using the original cable that came with it. It was my hunch that it may be a power issue as well. I bought a powered USB hub but might need to fiddle with how it's arranged a bit more. Hopefully that does the trick. Thanks everyone.

      Alright, so update. I bought a Y-Splitter and that seems to have done the trick. I managed to run gen2-age-gender and gen2-emotion-recognition (separately) via depthai-experiments. Yay!

      My question, and any help is appreciated, is what is the easiest way to run a simple object detection model?
      I've trained the model on Ultralytics and have also managed to upload a copy to Roboflow.
      The model works on the Ultralytics app (on my phone) and also works for still images on the Roboflow website.

        So I got an error for a stereo camera component. I thought I could make spatial=False in main.py and then just rerun main.py but it then just kills itself?

        (depthai-env) ali@luxonis:~/depthai/depthai-experiments/gen2-yolo/device-decoding $ python3 main.py --config model/Ali3.json

        config: model/Ali3.json

        And this is the code that came with main.py in gen2-yolo device decoding:

        from depthai_sdk import OakCamera, ArgsParser

        import argparse

        # parse arguments

        parser = argparse.ArgumentParser()

        parser.add_argument("-conf", "--config", help="Trained YOLO json config path", default='model/yolo.json', type=str)

        args = ArgsParser.parseArgs(parser)

        with OakCamera(args=args) as oak:

        color = oak.create_camera('color')

nn = oak.create_nn(args['config'], color, nn_type='yolo', spatial=True)

oak.visualize(nn, fps=True, scale=2/3)

oak.visualize(nn.out.passthrough, fps=True)

oak.start(blocking=True)

          Set a resolution manually to fix:

          Thanks ,

            So that would look like this?

            from depthai_sdk import OakCamera, ArgsParser
            import argparse
            # parse arguments

            parser = argparse.ArgumentParser()
            parser.add_argument("-conf", "--config", help="Trained YOLO json config path", default='model/yolo.json', type=str)
            args = ArgsParser.parseArgs(parser)

            with OakCamera(args=args) as oak:
            color = oak.create_camera('color', resolution=(640, 480))
            nn = oak.create_nn(args['config'], color, nn_type='yolo', spatial=True)
            oak.visualize(nn, fps=True, scale=2/3)
            oak.visualize(nn.out.passthrough, fps=True)
            oak.start(blocking=True)

              Yep. Make sure version is 1.15 and spatial=False since you are using oak-1

              Thanks,

                How do I change the version?
