Thanks for your report! Could you please provide your ONNX model? You can send me by email: daquexian566@gmail.com

It is a bug of pytorch->onnx converter. I have reported it to PyTorch: pytorch/pytorch#21271

[daquexian]

It is solved in pytorch/pytorch#21330. Please install nightly PyTorch and re-export the onnx model then try again.

thank u for reply, i have met the same problem ,could u tell me how to install nightly PyTorch? thank u very much

On https://pytorch.org/get-started/locally/, select "preview(nightly)" to get the command

[daquexian]

I believe pytorch/pytorch#21330 has been included in PyTorch 1.2, so it's better to install pytorch 1.2 than pytorch nightly
