Known Issues
Triton PIP wheels for ARM SBSA are not available from PyPI and pip will install an incorrect Jetson version of Triton for ARM SBSA. The correct wheel file can be pulled directly from the ARM SBSA SDK image and manually installed.

deepstream onnx part.2

생각해보니 deepstream onnx  github프로젝트의 경우

tiny_yolov2를 기반으로 작동하도록 libnvdsinfer_custom_bbox_tiny_yolo.so 를 생성했으니

ssd 와는 구조가 달라 당연히(?) 맞지 않으니 에러가 발생하고 죽는 듯.

azure의 custom vision 의 README에 기재된 링크를 가보았는데

onnx 포맷으로는 python과 c#만 제공하고

해당 사이트에서 python을 받아서 실행해보니 하나의 사진에 대해서 처리가 가능한 예제를 제공한다.

ssd deepstream 예제가 있는데

python 스크립트에 h264 elementary stream을 넣어주어야 한댄다

[링크 : https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/tree/master/apps/deepstream-ssd-parser]

 

-h h264가 포인트 인 듯.

$ ffmpeg -f video4linux2 -s 320x240 -i /dev/video0 -vcodec libx264 -f h264 test.264

[링크 : https://stackoverflow.com/questions/27090114/what-does-elementary-stream-mean-in-terms-of-h264]

 

JVT NAL sequence, H.264 라는 타입으로 변경된 듯.

sample_0.h264: JVT NAL sequence, H.264 video @ L 31
sample_0.mp4:  ISO Media, MP4 v2 [ISO 14496-14]

sample_ssd_relu6.uff 파일은 ssd inception v2 기반 모델인가?
