# YOLOv8-ONNXRuntime-Rust for All the Key YOLO Tasks |
|
|
|
This repository provides a Rust demo for performing YOLOv8 tasks like `Classification`, `Segmentation`, `Detection`, `Pose Detection` and `OBB` using ONNXRuntime. |
|
|
|
## Recently Updated |
|
|
|
- Add YOLOv8-OBB demo |
|
- Update ONNXRuntime to 1.17.x |
|
|
|
Newly updated YOLOv8 example code is located in this repository (https://github.com/jamjamjon/usls/tree/main/examples/yolov8) |
|
|
|
## Features |
|
|
|
- Support `Classification`, `Segmentation`, `Detection`, `Pose(Keypoints)-Detection`, `OBB` tasks. |
|
- Support `FP16` & `FP32` ONNX models. |
|
- Support `CPU`, `CUDA` and `TensorRT` execution provider to accelerate computation. |
|
- Support dynamic input shapes(`batch`, `width`, `height`). |
|
|
|
## Installation |
|
|
|
### 1. Install Rust |
|
|
|
Please follow the Rust official installation. (https://www.rust-lang.org/tools/install) |
|
|
|
### 2. Install ONNXRuntime |
|
|
|
This repository use `ort` crate, which is ONNXRuntime wrapper for Rust. (https://docs.rs/ort/latest/ort/) |
|
|
|
You can follow the instruction with `ort` doc or simply do this: |
|
|
|
- step1: Download ONNXRuntime(https://github.com/microsoft/onnxruntime/releases) |
|
- setp2: Set environment variable `PATH` for linking. |
|
|
|
On ubuntu, You can do like this: |
|
|
|
```bash |
|
vim ~/.bashrc |
|
|
|
# Add the path of ONNXRUntime lib |
|
export LD_LIBRARY_PATH=/home/qweasd/Documents/onnxruntime-linux-x64-gpu-1.16.3/lib${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}} |
|
|
|
source ~/.bashrc |
|
``` |
|
|
|
### 3. \[Optional\] Install CUDA & CuDNN & TensorRT |
|
|
|
- CUDA execution provider requires CUDA v11.6+. |
|
- TensorRT execution provider requires CUDA v11.4+ and TensorRT v8.4+. |
|
|
|
## Get Started |
|
|
|
### 1. Export the YOLOv8 ONNX Models |
|
|
|
```bash |
|
pip install -U ultralytics |
|
|
|
# export onnx model with dynamic shapes |
|
yolo export model=yolov8m.pt format=onnx simplify dynamic |
|
yolo export model=yolov8m-cls.pt format=onnx simplify dynamic |
|
yolo export model=yolov8m-pose.pt format=onnx simplify dynamic |
|
yolo export model=yolov8m-seg.pt format=onnx simplify dynamic |
|
|
|
|
|
# export onnx model with constant shapes |
|
yolo export model=yolov8m.pt format=onnx simplify |
|
yolo export model=yolov8m-cls.pt format=onnx simplify |
|
yolo export model=yolov8m-pose.pt format=onnx simplify |
|
yolo export model=yolov8m-seg.pt format=onnx simplify |
|
``` |
|
|
|
### 2. Run Inference |
|
|
|
It will perform inference with the ONNX model on the source image. |
|
|
|
```bash |
|
cargo run --release -- --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
Set `--cuda` to use CUDA execution provider to speed up inference. |
|
|
|
```bash |
|
cargo run --release -- --cuda --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
Set `--trt` to use TensorRT execution provider, and you can set `--fp16` at the same time to use TensorRT FP16 engine. |
|
|
|
```bash |
|
cargo run --release -- --trt --fp16 --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
Set `--device_id` to select which device to run. When you have only one GPU, and you set `device_id` to 1 will not cause program panic, the `ort` would automatically fall back to `CPU` EP. |
|
|
|
```bash |
|
cargo run --release -- --cuda --device_id 0 --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
Set `--batch` to do multi-batch-size inference. |
|
|
|
If you're using `--trt`, you can also set `--batch-min` and `--batch-max` to explicitly specify min/max/opt batch for dynamic batch input.(https://onnxruntime.ai/docs/execution-providers/TensorRT-ExecutionProvider.html#explicit-shape-range-for-dynamic-shape-input).(Note that the ONNX model should exported with dynamic shapes) |
|
|
|
```bash |
|
cargo run --release -- --cuda --batch 2 --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
Set `--height` and `--width` to do dynamic image size inference. (Note that the ONNX model should exported with dynamic shapes) |
|
|
|
```bash |
|
cargo run --release -- --cuda --width 480 --height 640 --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
Set `--profile` to check time consumed in each stage.(Note that the model usually needs to take 1~3 times dry run to warmup. Make sure to run enough times to evaluate the result.) |
|
|
|
```bash |
|
cargo run --release -- --trt --fp16 --profile --model <MODEL> --source <SOURCE> |
|
``` |
|
|
|
