How to get the ONNX from the official YOLOV8 PT File

This document describes how to convert the PT file provided by YOLOV8 to ONNX format.
The prerequisite is that the development environment for Python YOLOV8 has already been set up.

The requirement of ultralytics is in the file.

We supply the conda environment version list in the file.

1. Prepare Project File

Download from the GitHub:

git clone https://github.com/ultralytics/ultralytics.git
git checkout v8.2.77

2. Write Python code

Save the file as export. py

from ultralytics import YOLO

# Load a model
model = YOLO("yolov8n.pt")  # load a pretrained model

# export the model
model.export(format="onnx")  # export the model to ONNX format

3. Export the ONNX

python export.sh

4. Demo Video
