Segmentation fault

Hi,

I need to do inference on a Raspberry Pi 4B with NCS 2 using YOLO. I get the default model in IR (the xml and the bin file) before converting custom models to try, and used two demos of open_model_zoo but I always get a Segmentation fault error. Here are the outputs:

Command ./multi_channel_object_detection_demo_yolov3 -m ../../../build/frozen_darknet_yolov3_model.xml -d MYRIAD -i ../../../build/cars.mp4

Output: [ INFO ] InferenceEngine: IE version ......... 2021.4 Build ........... 0 [ INFO ] Parsing input parameters [ INFO ] Detection model: ../../../build/frozen_darknet_yolov3_model.xml [ INFO ] Detection threshold: 0.5 [ INFO ] Utilizing device: MYRIAD [ INFO ] Batch size: 1 [ INFO ] Number of infer requests: 5 [ INFO ] Model path: ../../../build/frozen_darknet_yolov3_model.xml Segmentation fault

Command ./object_detection_demo -m ../../../build/frozen_darknet_yolov3_model.xml -d MYRIAD -i ../../../build/cars.mp4 -at yolo

Output: [ INFO ] InferenceEngine: IE version ......... 2021.4 Build ........... 0 [ INFO ] Parsing input parameters [ INFO ] Reading input [ WARN:0] global ../opencv/modules/videoio/src/cap_gstreamer.cpp (1044) open OpenCV | GStreamer warning: unable to query duration of stream [ WARN:0] global ../opencv/modules/videoio/src/cap_gstreamer.cpp (1081) open OpenCV | GStreamer warning: Cannot query video position: status=1, value=0, duration=-1 [ INFO ] Loading Inference Engine [ INFO ] Device info: [ INFO ] MYRIAD myriadPlugin version ......... 2021.4 Build ........... 0 Loading network files [ INFO ] Batch size is forced to 1. [ INFO ] Checking that the inputs are as the demo expects [ INFO ] Checking that the outputs are as the demo expects [ INFO ] Loading model to the device Segmentation fault

I don’t know what could be the error or how to fix it. If anyone knows another way to do inference with YOLO on a Raspberry with the NCS it would be also good.

Thanks in advance

Adding that made it work. Thank you!!

@diego-varela-seijas could you try to add -DCMAKE_CXX_FLAGS="-march=armv7-a" to cmake command when you build OMZ demo?
