Troubleshooting

Q: Why is the performance on CPU sometimes better than on GPU, when running pipeline benchmarking like stream density?

A: The performance of pipeline benchmarking strongly depends on the models. Specifically for yolov5s object detection, it is recommended to use the model precision FP32 when it is running on device GPU. If supported, then you can change the model precision by updating the pipeline script to point to the precision of your choice. For example, you can change the model of FP16 to FP32 assuming the precision FP32 of the target model is available: 

    src/pipelines/yolov5s.sh

    ...
    model=models/object_detection/yolov5s/FP16-INT8/yolov5s.xml
    ...

Q: What happens if the system keeps crashing when building the dlstreamer-realsense image?

A: Some systems may run into issues with memory when building the dlstreamer-realsense image. In the Dockerfile.dlstreamer file, change the make command to not use the -j threading option.

- make -j"$(cat < /proc/cpuinfo |grep -c proc)" &&
+ make &&

Q: What happens if the RTSP source is not found?

A: Depending on your systems performance it is possible that the RTSP simulator may take additional time to initialize and start streaming. To avoid issues you can add a waiting period before the pipeline starts. For example you can add a 5 second sleep timer to /src/entrypoint.sh

sleep 5 # sleep for 5 seconds before starting the pipeline
eval $gstLaunchCmd

Q: How can I use an Intel RealSense Camera as the input?

A: To use a RealSense camara as an input for any of the retail use cases, you need to obtain the serial number first. Follow the instructions here to run rs-enumerate-devices and obtain the following information:

Device Name                   Serial Number       Firmware Version
Intel RealSense D415          725112060400        05.12.02.100
Device info:
    Name                          :     Intel RealSense D415
    Serial Number                 :     725112060400
    Firmware Version              :     05.12.02.100
    Recommended Firmware Version  :     05.12.02.100
    Physical Port                 :     \\?\usb#vid_8086&pid_0ad3&mi_00#6&2a371216&0&0000#{e5323777-f976-4f5b-9b55-b94699c46e44}\global
    Debug Op Code                 :     15
    Advanced Mode                 :     YES
    Product Id                    :     0AD3
    Camera Locked                 :     NO
    Usb Type Descriptor           :     3.2
    Product Line                  :     D400
    Asic Serial Number            :     012345678901
    Firmware Update Id            :     012345678901

Simply add the serial number to the INPUTSRC argument when calling the pipelines:

INPUTSRC=725112060400 make run-demo
