I downgraded the ONNX model version to 9 to fit 19041, but it still doesn't work!

###@martinb35 My code:

       onnx.export(model,
            md_input,
            "out/eye.onnx",
            export_params=True,
            opset_version=9,
            verbose=False,
            do_constant_folding=True,
            input_names=['In'],
            output_names=['Out'],
            dynamic_axes={'In':{0:'batch_size'},
                          'Out':{0:'batch_size'}},
            # keep_initializers_as_inputs=True,
            )

I exported the PyTorch model with the above code and set the OP version to 9, but still got an error： Parameter error Failed to load model with error: Unknown model file format

I have tried all kinds of methods, but it still doesn't work. Is there any way to solve this problem? Thanks!

Hi @Lookforworld, do you mind sharing your model for reproduction purposes?
