Triton Inference Server Client For YOLO Models

The Triton Inference Server simplifies the deployment of machine learning models with a plethora of out-of-the-box benefits, including a GRPC and HTTP interface, automatic scheduling on multiple GPUs, shared memory utilization (even on GPUs), dynamic server-side batching, health metrics, and memory resource management.

This repository utilizes the Triton Inference Server Client, which streamlines the complexity of model deployment.
The client is lightweight and requires minimal infrastructure, making it an ideal choice for deploying/testing YOLO models efficiently.

This repository is a continuation of the work on Triton Client by Philipp Schmidt, available here.

Enhancements

  • Added support for evaluating the model using the COCO dataset with models built on TensorRT engines.

Triton Server

Make sure that the Triton Server is up and running with the required models. To set up the Triton Server, you can utilize the repository triton-server-yolo.

Install Triton Client YOLO

# recommended use python virtual environment
git clone https://github.com/levipereira/triton-client-yolo.git
cd triton-client-yolo
pip install -r requirements.txt

Evaluating Coco Dataset on Yolo Models.

Prerequisite

Download Coco Dataset Manually.

bash ./scripts/get_coco.sh

Start Triton Server in Evaluation Mode triton-server-using-models-for-evaluation-purposes

How to Evalulate Coco Dataset

Example:

python3 coco_eval.py --model yolov9-c --data data/coco.yaml

Inference your own data

Example client can be found in client.py. It can run dummy input, images and videos.

python3 client.py image --model yolov9-e data/dog.jpg
