# YOLOv8-Segmentation-ONNXRuntime-Python Demo

This repository provides a Python demo for performing segmentation with YOLOv8 using ONNX Runtime, highlighting the interoperability of YOLOv8 models without the need for the full PyTorch stack.

## Features

- **Framework Agnostic**: Runs segmentation inference purely on ONNX Runtime without importing PyTorch.
- **Efficient Inference**: Supports both FP32 and FP16 precision for ONNX models, catering to different computational needs.
- **Ease of Use**: Utilizes simple command-line arguments for model execution.
- **Broad Compatibility**: Leverages Numpy and OpenCV for image processing, ensuring broad compatibility with various environments.

## Installation

Install the required packages using pip. You will need `ultralytics` for exporting YOLOv8-seg ONNX model and using some utility functions, `onnxruntime-gpu` for GPU-accelerated inference, and `opencv-python` for image processing.

```bash

pip install ultralytics

pip install onnxruntime-gpu  # For GPU support

# pip install onnxruntime    # Use this instead if you don't have an NVIDIA GPU

pip install numpy

pip install opencv-python

```

## Getting Started

### 1. Export the YOLOv8 ONNX Model

Export the YOLOv8 segmentation model to ONNX format using the provided `ultralytics` package.

```bash

yolo export model=yolov8s-seg.pt imgsz=640 format=onnx opset=12 simplify

```

### 2. Run Inference

Perform inference with the exported ONNX model on your images.

```bash

python main.py --model-path <MODEL_PATH> --source <IMAGE_PATH>

```

### Example Output

After running the command, you should see segmentation results similar to this:

## Advanced Usage

For more advanced usage, including real-time video processing, please refer to the `main.py` script's command-line arguments.
