PP-OCRv4_server_det ONNX

ONNX conversion of PaddlePaddle's official PP-OCRv4_server_det text detection inference model.

Provenance

Upstream archive: https://paddle-model-ecology.bj.bcebos.com/paddlex/official_inference_model/paddle3.0.0/PP-OCRv4_server_det_infer.tar
Upstream projects: PaddleOCR and PaddleX
Conversion environment: PaddlePaddle 3.3.0, PaddleX 3.7.0, paddle2onnx 2.0.2rc3
ONNX opset: 11

Validation

The graph passed onnx.checker, loaded and ran with ONNX Runtime 1.28.0 on CPU, and was compared numerically with the original Paddle inference graph using the same deterministic float32 input. Maximum absolute output error: 1.280568540096283e-7.
