As for import/export issue, I understand current support functionality for PyTorch and Caffe2.

https://github.com/onnx/tutorials/blob/master/README.md 3
https://github.com/caffe2/caffe2/blob/master/caffe2/python/onnx/ONNXOpCoverage.md 8

Is there any issue related to “import ONNX model to PyTorch” in PyTorch issue?
