Hi, there. I'd like to transfer a PaddleOCR model to onnx, the procedure I followed is from https://github.com/PaddlePaddle/PaddleOCR/issues/213 . According to the issue, the author succeeded, but I failed during my trial.

Model:

I downloaded the PaddleOCR model from: https://paddleocr.bj.bcebos.com/ch_models/ch_det_mv3_db_infer.tar And I renamed them to__model__ and__params__, according to issue 213.

Procedure:

git clone https://github.com/PaddlePaddle/X2Paddle.git
cd X2Paddle
python setup.py install
pip install paddlepaddle
x2paddle -f paddle2onnx -m ../ch_det_mv3_db -s ./output

And the error message is:

paddle.__version__ = 1.8.4
Now, onnx2paddle support convert onnx model opset_verison [9, 10, 11],opset_verison of your onnx model is 10, automatically treated as op_set: 10.
Translating PaddlePaddle to ONNX...

Great appreciate if anyone could help me with this. Thanks~
