PytorchCaffe2SuperResolution caffe result dismatch pytorch result

[cswwp]

i had tested this demo on my cpu machine, and i modify the model_zoo.load_url(model_url, map_location='cpu') with cpu model load, but the reuslt np.testing.assert_almost_equal(torch_out.data.cpu().numpy(), c2_out, decimal=3) shows: (mismatch 99.89082872732426%) x: array([-0.047, 0.17 , 0.84 , ..., 0.204, 0.15 , 0.142], dtype=float32) y: array([-0.047, 1.371, 1.373, ..., 0.577, 0.355, 0.142], dtype=float32) I don't know what happen, and how fix it? anyone help?

I have a similar issue. I do not know if the UserWarning is related to the accuracy problem or not.

/home/developer/anaconda3/envs/PyTorch/lib/python3.6/site-packages/onnx_caffe2/backend.py:521: UserWarning: This version of onnx-caffe2 targets ONNX operator set version 2, but the model we are trying to import uses version 9. We will try to import it anyway, but if the model uses operators which had BC-breaking changes in the intervening versions, import will fail. warnings.warn("This version of onnx-caffe2 targets ONNX operator set version {}, but the model we are trying to import uses version {}. We will try to import it anyway, but if the model uses operators which had BC-breaking changes in the intervening versions, import will fail.".format(cls._known_opset_version, imp.version))

We run the conversion of Super Resolution in CI: https://github.com/pytorch/pytorch/blob/master/test/onnx/test_pytorch_onnx_caffe2.py#L429

And we compare the results, it should be fine

Any update on this? Same error, the predictions doesn't match.
