Export custom ops (#29752)
Summary:
Updated to export API:
When calling this API, a dict containing the custom opsets (domain and version) used to export the model could be provided.
We allow registering one custom opset (domain, version) per ONNX opset. So, when exporting an operator from a custom domain, users need to pass this pair. Default custom opset version is 1.
