Thank you too. Let me clarify why I was eager to find a way to make Caffe2 work with recent opset. I’ve recently worked with your repo with AICamera that manages PyTorch v1.0.0  to work with Android devices using Caffe2 library. So I know that right now it is TorchScript available in mobile and onnx-runtime doesn’t work with mobile. So I wondered how to deploy on mobile ONNX model with recent opset using Caffe2 backend.
P.S. The last statement is not a question just a theme to discuss
