    I have trained a custom object detection model for VOXL2 and already deployed it using voxl-cross. To test it, I do voxl-configure-tflite and select my custom model to work with high-res camera.

    My custom model is based on mobilenetv2, trained using tflite mediapipe library exactly the way shown here: https://colab.research.google.com/github/googlesamples/mediapipe/blob/main/examples/customization/object_detector.ipynb#scrollTo=Mz3-eHe07FEX

    The problem is that my model loads up and shows on the VOXL portal under tflite on multi-view page, but does not draw any bounding boxes around the objects. I'm not sure what's wrong and trying to debug it going through entire tflite source code. I wanted to see the outputs of fprintf(stderr,...) in the source code but not sure how to access that. Any suggestions?

    Thanks

      @arcj voxl-tflite-server is likely running as a systemd service.

      For debugging purposes I would disable it from running on boot with the following:

      systemctl disable voxl-tflite-server
      

      and also kill it

      systemctl stop voxl-tflite-server
      

      then run voxl-tflite-server from the command line to monitor the output

        @tom said in Where to see fprintf messages coming from voxl-tflite-server?:

        systemctl stop voxl-tflite-server

        Still I can't see the outputs of fprintf(stderr,...)

          @arcj Try voxl-tflite-server -d
