a full path to the destination.
                In that case, besides saving the ONNX model, a folder with "_initializers" suffix (without extension)
                will be created to store the each initializer of the ONNX model in a separate file. For example, if the
                destination is "/path/model.onnx", the initializers will be saved in "/path/model_initializers/" folder.
            model_state_dict: The state_dict of the PyTorch model containing all weights on it.
                It can be either a dict as returned by :meth:`model.state_dict`, or a string with a file name.
                Required when :func:`enable_fake_mode` is used but real initializers are needed on the ONNX graph.
                It can be either a string with the path to a checkpoint or a dictionary with the actual model state.

            serializer: The serializer to use. If not specified, the model will be serialized as Protobuf.
