As what has been repeatedly pointed in #2049, the opset version in the URLs of models should not be
onnx.des.onnx_opset_version()
. After waiting for a fix for a long time, I found it is easy to fix by maintaining a separate opset version.The opset version should have been updated to 11 (the opset version of the latest stable release of ONNX), but URLs like https://s3.amazonaws.com/download.onnx/models/opset_11/vgg19.tar.gz are still invalid :| They seems ignored by ONNX maintainers. In order to keep fresh contributors from feeling confused and frustrated as soon as possible, I set the opset version to 10 for now.
