为什么导出paraformer streaming模型只能导出encoder和decoder部分，不能导出predicator部分

[yuwei-star]

def export_rebuild_model(model, **kwargs): # self.device = kwargs.get("device") is_onnx = kwargs.get("type", "onnx") == "onnx" encoder_class = tables.encoder_classes.get(kwargs["encoder"] + "Export") model.encoder = encoder_class(model.encoder, onnx=is_onnx)

predictor_class = tables.predictor_classes.get(kwargs["predictor"] + "Export")
model.predictor = predictor_class(model.predictor, onnx=is_onnx)

if kwargs["decoder"] == "ParaformerSANMDecoder":
    kwargs["decoder"] = "ParaformerSANMDecoderOnline"
decoder_class = tables.decoder_classes.get(kwargs["decoder"] + "Export")
model.decoder = decoder_class(model.decoder, onnx=is_onnx)

from funasr.utils.torch_function import sequence_mask

model.make_pad_mask = sequence_mask(max_seq_len=None, flip=False)

import copy
import types

encoder_model = copy.copy(model)
decoder_model = copy.copy(model)

# encoder
encoder_model.forward = types.MethodType(export_encoder_forward, encoder_model)
encoder_model.export_dummy_inputs = types.MethodType(export_encoder_dummy_inputs, encoder_model)
encoder_model.export_input_names = types.MethodType(export_encoder_input_names, encoder_model)
encoder_model.export_output_names = types.MethodType(export_encoder_output_names, encoder_model)
encoder_model.export_dynamic_axes = types.MethodType(export_encoder_dynamic_axes, encoder_model)
encoder_model.export_name = "model"  # types.MethodType(export_encoder_name, encoder_model)

# decoder
decoder_model.forward = types.MethodType(export_decoder_forward, decoder_model)
decoder_model.export_dummy_inputs = types.MethodType(export_decoder_dummy_inputs, decoder_model)
decoder_model.export_input_names = types.MethodType(export_decoder_input_names, decoder_model)
decoder_model.export_output_names = types.MethodType(export_decoder_output_names, decoder_model)
decoder_model.export_dynamic_axes = types.MethodType(export_decoder_dynamic_axes, decoder_model)
decoder_model.export_name = "decoder"  # types.MethodType(export_decoder_name, decoder_model)

return encoder_model, decoder_model

使用官方教程from funasr import AutoModel

model = AutoModel(model="paraformer")

res = model.export(quantize=False)的导出导出代码，可以导出两个onnx文件，model.onnx和decoder.onnx，其中model.onnx查看输入输出后发现是encoder部分，decoder.onnx是decoder部分，请问怎么导出完整的paraformer streaming onnx模型呢
