# Exporting 🤗 Transformers models to ONNX
|
|
|
|
🤗 Transformers provides a `transformers.onnx` package that enables you to
|
|
convert model checkpoints to an ONNX graph by leveraging configuration objects.
|
|
|
|
See the [guide](../serialization) on exporting 🤗 Transformers models for more
|
|
details.
|
|
|
|
## ONNX Configurations
|
|
|
|
We provide three abstract classes that you should inherit from, depending on the
|
|
type of model architecture you wish to export:
|
|
|
|
* Encoder-based models inherit from [`~onnx.config.OnnxConfig`]
|
|
* Decoder-based models inherit from [`~onnx.config.OnnxConfigWithPast`]
|
|
* Encoder-decoder models inherit from [`~onnx.config.OnnxSeq2SeqConfigWithPast`]
|
|
|
|

### OnnxSeq2SeqConfigWithPast

## ONNX Features
|
|
|
|
Each ONNX configuration is associated with a set of _features_ that enable you
|
|
to export models for different types of topologies or tasks.
