How to custome model with Jetson Platform Services (JPS)?

Accelerated Computing Intelligent Video Analytics Metropolis Microservices for Jetson
1

I have an idea about Jetson Platform Services i.e. JPS through Quick Start Guide — Metropolis on Jetson documentation 0.1.0 documentation and DeepStream Perception — Metropolis on Jetson documentation 0.1.0 documentation

I come across this git directory : GitHub - NVIDIA-AI-IOT/jetson-platform-services: A collection of reference AI microservices and workflows for Jetson Platform Services

how can I integrate let’s say, the License Plate Recognition model from NGC with JPS instead of the default peoplenet or YoloV8 model? Can anyone suggest steps to follow?

Do you mean you want to integrate this project: GitHub - NVIDIA-AI-IOT/deepstream_lpr_app: Sample app code for LPR deployment on DeepStream into JPS?

Thanks for your quick response.

Yes, I wanted to integrate the same project.

There are three models (PGIE(car detection) → SGIE(car license plate detection) → SGIE(car license plate recognization)) in deepstream_lpr_app sample. JPS deepstream microservices use deepstream-test5 sample. I think you need to port those three models into deepstream-test5 sample. You also need modify Redis message schema for LPR application.

I tried the steps mentioned in the https://github.com/NVIDIA-AI-IOT/deepstream_lpr_app/tree/master on the Jetson Orin Nano but could not figure out how to use the tao-converter on it.

There are multiple issues open for the same repo. Does this app support the deepstream 7.0?

To run on the JPS is a very far question.

Yes, LPR sampe works for DeepStream SDK 6.0 or above.

Okay, I follow all the steps mentioned in deepstream_lpr_app/deepstream-lpr-app/lpr_app_infer_us_config.yml at master · NVIDIA-AI-IOT/deepstream_lpr_app · GitHub

My device is Jetson Orin Nano

When I run the

Blockquote
t-tech@ubuntu:~/deepstream_lpr_app/deepstream-lpr-app$ ./deepstream-lpr-app lpr_app_infer_us_config.yml
use_nvinfer_server:0, use_triton_grpc:0
Request sink_0 pad from streammux
One element could not be created. Exiting.

Where am I making mistake?
