            create_args: A function that creates positional inputs for the model.
            create_kwargs: A function that creates keyword inputs for ther model.
            load_checkpoint_during_init: Whether to load a checkpoint during model initialization.
                (after or during model creation, but before exporting starts)
            export_within_fake_mode: Whether to call torch.onnx._dynamo_export within torch._subclasses.FakeTensorMode
            model_type: Type of user model. Used to determine whether the user model must be exported to
                torch.export.ExportedProgram before passing it to torch.onnx.dynamo_export

        This test contains several steps.

        1. Create a toy model.
        2. Save the toy's state (parameters) to a file. This is for simulating a checkpoint file.
        3. Load it back and export it to ONNX with Fake Mode enabled.
            Because all operations (including model and input loading) are done under
            FakeTensorMode, no real tensor are created and no real computation happens.
        4. The ONNX model generated in step 3 doesn't contain parameters,
            and this step adds them as external data on an ONNX model.
        5. Run PyTorch and ONNX models and compare their results.
