public class MyMetadataCallbackHandler : IONNXMetadataImportCallbackReceiver
{
    public ONNXModelMetadata Metadata { get; private set; }

    // Callback for metadata import. Member Metadata is of type ONNXModelMetadata.
    public void OnMetadataImported(AssetImportContext ctx, ONNXModelMetadata metadata)
    {
        Metadata = metadata;
    }
}

Methods

OnMetadataImported(AssetImportContext, ONNXModelMetadata)

This method is called when metadata is loaded during ONNX import, before the model is serialized.

Parameters
Type Name Description
AssetImportContext ctx

The context of the current import process.
ONNXModelMetadata metadata

Remarks

Interface for handling metadata during the import process. It provides a way to store metadata for later access and optionally create additional assets using the AssetImportContext. in a way that it can be accessed later. The AssetImportContext is provided to so that additional assets can be created and added to the import context, if necessary. Note that the model itself is not available in the AssetImportContext at this point.
