# 导出 🤗 Transformers 模型到 ONNX

🤗 Transformers提供了一个`transformers.onnx`包，通过利用配置对象，您可以将模型checkpoints转换为ONNX图。

有关更多详细信息，请参阅导出 🤗 Transformers 模型的[指南](../serialization)。

## ONNX Configurations

我们提供了三个抽象类，取决于您希望导出的模型架构类型：

* 基于编码器的模型继承 [`~onnx.config.OnnxConfig`]
* 基于解码器的模型继承 [`~onnx.config.OnnxConfigWithPast`]
* 编码器-解码器模型继承 [`~onnx.config.OnnxSeq2SeqConfigWithPast`]

### OnnxConfig

### OnnxConfigWithPast

### OnnxSeq2SeqConfigWithPast

## ONNX Features

每个ONNX配置与一组 _特性_ 相关联，使您能够为不同类型的拓扑结构或任务导出模型。
