AliChoudhry I could view the desktop and browse the internet and such. I did use the RPi imager instead of the Baleana Etcher as the Etcher was giving me problems.

Then you are already using the RPI. No further SSH connecting is needed.

The device should work now.

AliChoudhry I did try to run one of the tests to see if the camera is attached (I think it was in the deptha folder?) and the camera test passed.

Good.

AliChoudhry The camera seems to be connected; however I can't seem to run any NN/inference. For example I couldn't run the sample "age-gender" program in the examples, nor "tiny-yolo" in the examples.

Any particular error you are experiencing? If ColorCamera/rgb_preview.py example runs, all other should as well.

Thanks,
Jaka

        I retested rgb_preview.py and it works. However, yolo gave this: depthai-python) ali@luxonis:~/depthai-python/examples/Yolo $ python tiny_yolo.py

          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.

                4 days later

                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?

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

                with OakCamera(args=args) as oak:

                  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,
