Common API for exporters. By default, the models are optimized to use the most efficient kernels implemented in onnxruntime.

Parameters:

  • mod – torch model

  • args – unnamed arguments

  • kwargs – named arguments

  • input_names – input names for the onnx model (optional)

  • target_opset – opset to target, if not specified, each converter keeps its default value

  • verbose – verbosity level

  • dynamic_shapes – dynamic shapes, usually a nested structure included a dictionary for each tensor

  • filename – output filename

  • output_names – to change the output of the onnx model

  • output_dynamic_shapes – to overwrite the dynamic shapes names

  • exporter – exporter to use (onnx-dynamo, modelbuilder, custom)

Returns:

the output of the selected exporter, usually a structure including an onnx model

A simple example:

to_onnx(
    model,
    kwargs=inputs,
    dynamic_shapes=ds,
    exporter=exporter,
    filename=filename,
)
