PaddleOCR ONNX Models

🔥 ONNX format models converted from PaddleOCR for easy deployment and testing

📖 Model Description

This repository contains ONNX format models converted from PaddleOCR, a practical ultra-lightweight OCR system. These models are optimized for production deployment and cross-platform compatibility.

Basic Usage

import onnxruntime as ort
import numpy as np
from PIL import Image

# Load detection model
det_session = ort.InferenceSession("models/PP-OCRv5_server_det_infer.onnx")

# Load recognition model  
rec_session = ort.InferenceSession("models/PP-OCRv5_server_rec_infer.onnx")
