I am testing OAK-D LR on Ubuntu 20.04 system. I could not get stereo images following the instruction of depthai repo and depthai_ros too.
1. depthai, in main branch Aug 29 (commit f319764940b003799987850eca56ea84da911eb4)
After building the docker image, run
docker run --privileged -v /dev/bus/usb:/dev/bus/usb --device-cgroup-rule='c 189:* rmw' -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --network host --rm -i -t depthai:latest python3 /depthai/depthai_demo.py
Got GUI and can view real time rgb, but not stereo image (left, right, depth). In the log printed, there is an error as below.

    Hi Jaka,

    I feel like the necessary information is already included in the original post. What else do you need me to provide?

      Hi jeffrrrrrr
      Oh, my bad I thought you were running a custom script. The demo afaik does not support devices that use color cameras for stereo. I suggest you use depthai-viewer, or the cam_test.py script available inside the depthai-python repo.

      Thanks,
      Jaka

        Hi Jaka,

        Thanks for the reply. Actually what i need to use is the ros wrapper that publishes stereo image pairs.
        But i tested depthai-viewer, and it did not work neither. Here is the environment and situation.

        Ubuntu 20.04
        python 3.8.10 (venv)
        pip3 (23.2.1)
        I tried pip3 install depthai-viewer, also using the whl from this page https://github.com/luxonis/depthai-viewer/releases/tag/v0.1.4
        After launching depthai-viewer (0.1.4), it installs dependencies but failed.
        > depthai-viewer

        depthai-sdk 1.11.0 requires depthai==2.21.2, but you have depthai 2.22.0.0 which is incompatible.

          jeffrrrrrr depthai-sdk 1.11.0 requires depthai==2.21.2, but you have depthai 2.22.0.0 which is incompatible.

          Probably the reason. The depthai will by default install 2.21.2 since that is what works with the demo script. Could you downgrade the depthai library to 2.21.1.

          Thanks,
          Jaka

            I tried it as well. but it does not work. Could you tell me which version of depthai-viewer is supported, including pip version?

              Hi jeffrrrrrr
              Could you try running python3 -m pip install depthai-viewer==0.1.3 --force-reinstall.

              Thanks,
              Jaka

                hi Jaka, this command seems working, tho with the same error message.

                ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

                Do you have some idea about how to make it work?

                Hi Jaka,

                Besides, could you give me instructions to run the ros node for OAK-D-LR camera please?

                Thanks
                Jeff

                  hi Adam,

                  @Luxonis-Adam Could you help to take a look at the ros related issue as I posted originally please?

                  Thanks,
                  Jeff

                  Hi, OAK-D-LR should run fine with depthai-ros-driver. Until version v2.8.0 is released you will need to set individual sensor resolution (1200p) in driver parameters. If you have any further issues, please create an issue on Github and we will address it there.

                  Best,
                  Adam

                  Hi Adam,

                  Thanks for your reply. Could you point out where to set the resolution, or sharing an example camera.yaml with me please?

                  Hi, to set resolution you need to specify SENSOR_NAME_i_resolution parameter, example can be found here
