• DepthAI-v2

  • 'depthai.DeviceInfo' object has no attribute 'name'

Hello,
I'm not sure exactly how this happened.
Execute utility device manger in deptha-python, and search is found in select Device, but there is nothing inside, and terminal and pop-up window

terminal output
"Exception in /depthai-python/utilities/device_manager.py, line 830; 'depthai.DeviceInfo' object has no attribute 'name' `

I also tried factory reset in Danger Zone, but same result.
Of course, the camera doesn't work.
Is it a firmware error?
How should I do the solution?

  • Hi yeo
    Do a python3 -m pip install depthai==2.22.0. You should be fine.

    Thanks,

      Hi yeo
      You probably have an outdated version of the depthai-python repo. You will need to update it to the latest ver. Let me know if this is the case here.

      Thanks,

          I did a depthai-python git clone yesterday.

          And when running the example code, I can't even hear a "Click?" sound

              yeo Ok, the repo should be up to date then. What about the depthai version? Do a pip3 show depthai.

              Thanks,

                  Name: depthai
Version: 2.17.2.0

                  How can I re-update the camera firmware when it is broken?

                          jakaskerl changed the title to 'depthai.DeviceInfo' object has no attribute 'name' .

                          I would be curious to know how this got resolved.

                          I use depth Version: 2.22.0.0, but I get the following error:

                          Connected cameras: [{socket: CAM_A, sensorName: IMX214, width: 4208, height: 3120, orientation: AUTO, supportedTypes: [COLOR], hasAutofocus: 1, name: color}, {socket: CAM_B, sensorName: OV7251, width: 640, height: 480, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, name: left}, {socket: CAM_C, sensorName: OV7251, width: 640, height: 480, orientation: AUTO, supportedTypes: [MONO], hasAutofocus: 0, name: right}]

                          AttributeError: 'depthai.Device' object has no attribute 'getProductName'

                          I tried running python3 -mpip install depthai -U but the terminal eventually stops with the following error: ERROR: Failed building wheel for depthai

                          I am running out of ideas 🙁

                            Hi srecouvreur
                            It's not a depthai issue, but EEPROM one. The device has been flashed some time ago and doesn't have the product field (you can check that with Eeprom reader script).
                            Just remove the getProductName() call from inside the script and it should work.

                            Thanks,
                            Jaka

                              Okay, interestingly the code I was using from the Github repo (below) doesn't have that getProductName() call, despite showing as an error in the log

                              #!/usr/bin/env python3

                              import cv2import depthai as dai
                              # Create pipelinepipeline = dai.Pipeline()
                              # Define source and outputcamRgb = pipeline.create(dai.node.ColorCamera)xoutVideo = pipeline.create(dai.node.XLinkOut)
                              xoutVideo.setStreamName("video")
                              # PropertiescamRgb.setBoardSocket(dai.CameraBoardSocket.CAM_A)camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)camRgb.setVideoSize(1920, 1080)
                              xoutVideo.input.setBlocking(False)xoutVideo.input.setQueueSize(1)
                              # LinkingcamRgb.video.link(xoutVideo.input)
                              # Connect to device and start pipelinewith dai.Device(pipeline) as device:
                              video = device.getOutputQueue(name="video", maxSize=1, blocking=False)
                              while True: videoIn = video.get()
                              # Get BGR frame from NV12 encoded video frame to show with opencv # Visualizing the frame on slower hosts might have overhead cv2.imshow("video", videoIn.getCvFrame())
                              if cv2.waitKey(1) == ord('q'): break

                              But implementing the older documentation code instead and commenting out line 33 (with that specific call)… it works!

                              Is it possible that the current (new) code in the repository is erroneous?

                                Ah sorry I got mixed up between the different examples I was trying to run - all good 🙂
