   --monolith            Force to export the model as a single ONNX file. By default, the ONNX exporter may break the model in several ONNX files, for example for encoder-decoder models where the encoder should be run only once while the decoder is looped over.
   --device DEVICE       The device to use to do the export. Defaults to "cpu".
   --opset OPSET         If specified, ONNX opset version to export the model with. Otherwise, the default opset will be used.
