Paddle检测模型转ONNX，onnxruntime时报错

[maximli]

paddle2onnx --model_dir ./model/ --model_filename inference.pdmodel --params_filename inference.pdiparams --save_file ./model/det_large.onnx --opset_version 10 --enable_onnx_checker True

转为onnx没有报错
2021-09-16 15:52:58 [INFO] ONNX model generated is valid.
2021-09-16 15:52:58 [INFO] ONNX model saved in ./model/det_large.onnx

onnx.load 成功，在这步时报错
sess = ort.InferenceSession(onnx_model.SerializeToString())

onnxruntime.capi.onnxruntime_pybind11_state.InvalidArgument: [ONNXRuntimeError] : 2 : INVALID_ARGUMENT : Failed to load model with error: /Users/runner/work/1/s/onnxruntime/core/graph/model.cc:111 onnxruntime::Model::Model(onnx::ModelProto &&, const onnxruntime::PathString &, const onnxruntime::IOnnxRuntimeOpSchemaRegistryList *, const logging::Logger &) Unknown model file format version.

=======问题已解决 Problem solved======

原因： onnxruntime目前不支持高版本的onnx，导致加载出错
解决方案： 降低环境中onnx的版本至1.6.0~1.9.0 ，重新导出ONNX模型即可

Why: Currently, onnx>=1.10.0 is not supported by onnxruntime<=1.9.0
How to solve: downgrade onnx to 1.6.0~1.9.0, and convert paddle model to onnx again.

pip install onnx==1.7.0

请问你的onnx和onnxruntime版本是？请参照#327

[maximli]

本地配置如下，模型时gpu下训练出来的。
onnx 1.10.1
onnxruntime 1.8.1
paddle 1.0.1
paddle2onnx 0.8
paddlepaddle 2.0.0

@maximli Currently, we found that onnx>=1.10.0 is not supported by onnxruntime<=1.9.0, refer here https://github.com/microsoft/onnxruntime/blob/master/docs/Versioning.md for more information.

To convert paddle model and use onnxruntime successfully, please make sure

• paddle2onnx >= 0.8.0
• onnx <= 1.9.0
• onnxruntime >=1.8.0

[maximli]

谢谢，重新安装onnx为1.9.0，有如下报错

onnx.onnx_cpp2py_export.checker.ValidationError: Your model ir_version is higher than the checker's.

[maximli]

哦，需要重新生成onnx文件。目前正常了，十分感谢！@jiangjiajun @yeliang2258

使用命令：paddle2onnx --model_dir D:\111\paddle-model-1 --model_filename model.pdmodel --params_filename model.pdiparams -s rec.onnx --opset_version 11 --enable_onnx_checker True 后重新生成onnx文件仍然报onnxruntime::Model::Model Unknown model file format version.这个错。

环境：
python==3.8
paddle2onnx==1.0.1
onnxruntime==1.8.1
onnx==1.9.0 或者 1.7.0 都试过

[yeliang2258]

麻烦升级onnx和onnxruntime到1.11以上

[jindameias]

麻烦升级onnx和onnxruntime到1.11以上

感谢哥哥，onnxruntime==1.11.0 and onnx==1.11.0已经成功加载

[Wangyongdi]

麻烦升级onnx和onnxruntime到1.11以上

cuda版本不支持高版本onnxruntime怎么办啊 ？
cuda-10.2，onnxruntime-1.6.0，onnx-1.7.0，paddle2onnx-1.0.1 还是报这个错误

[jiangjiajun]

@Wangyongdi 解决方案参考这里第3个问题https://github.com/PaddlePaddle/Paddle2ONNX/blob/develop/docs/zh/FAQ.md
