Paddle2ONNX
简体中文 | English
1 Paddle2ONNX 简介
Paddle2ONNX 支持将 PaddlePaddle 模型格式转化到 ONNX 模型格式。通过 ONNX 可以完成将 Paddle 模型到多种推理引擎的部署，包括 TensorRT/OpenVINO/MNN/TNN/NCNN，以及其它对 ONNX 开源格式进行支持的推理引擎或硬件。
2 Paddle2ONNX 环境依赖
Paddle2ONNX 依赖PaddlePaddle3.0，我们建议您在以下环境下使用 Paddle2ONNX ：
- PaddlePaddle == 3.0.0
- onnxruntime >= 1.10.0
3 安装 Paddle2ONNX
如果您只是想要安装 Paddle2ONNX 且没有二次开发的需求，你可以通过执行以下代码来快速安装 Paddle2ONNX
pip install paddle2onnx
如果你希望对 Paddle2ONNX 进行二次开发，请按照Github 源码安装方式编译Paddle2ONNX。
4 快速使用教程
4.1 获取PaddlePaddle部署模型
Paddle2ONNX 在导出模型时，需要传入部署模型格式，包括两个文件
model_name.json: 表示模型结构model_name.pdiparams: 表示模型参数
4.2 调整Paddle模型
如果对Paddle模型的输入输出需要做调整，可以前往Paddle 相关工具查看教程。
4.3 使用命令行转换 PaddlePaddle 模型
你可以通过使用命令行并通过以下命令将Paddle模型转换为ONNX模型
paddle2onnx --model_dir model_dir \
--model_filename model.json \
--params_filename model.pdiparams \
--save_file model.onnx
可调整的转换参数如下表:
| 参数 | 参数说明 |
|---|---|
| --model_dir | 配置包含 Paddle 模型的目录路径 |
| --model_filename | [可选] 配置位于 --model_dir 下存储网络结构的文件名 |
| --params_filename | [可选] 配置位于 --model_dir 下存储模型参数的文件名 |
| --save_file | 指定转换后的模型保存目录路径 |
| --opset_version | [可选] 配置转换为ONNX的OpSet版本，目前支持7~19等多个版本，默认为 9 |
| --enable_auto_update_opset | [可选] 是否开启opset version自动升级功能，当低版本opset无法转换时，自动选择更高版本的opset进行转换， 默认为 True |
| --enable_onnx_checker | [可选] 配置是否检查导出为 ONNX 模型的正确性, 建议打开此开关， 默认为 True |
| --enable_dist_prim_all | [可选] 是否开启组合算子拆解，默为 False |
| --optimize_tool | [可选] ONNX模型优化工具，可选择onnxoptimizer、polygraphy、None, 默认为 onnxoptimizer |
| --enable_verbose | [可选] 是否打印更更详细的日志信息，默认为 False |
| --version | [可选] 查看 paddle2onnx 版本 |
4.4 裁剪ONNX
如果你需要调整 ONNX 模型，请参考 ONNX 相关工具
4.5 优化ONNX
如你对导出的 ONNX 模型有优化的需求，推荐使用 onnxslim 对模型进行优化:
pip install onnxslim
onnxslim model.onnx slim.onnx
5 代码贡献
繁荣的生态需要大家的携手共建，开发者可以参考 Paddle2ONNX 贡献指南 来为 Paddle2ONNX 贡献代码。
