After upgrading to the latest Windows 10 Oct 2018 release, the exported Custom Vision ONNX model cannot be loaded by the WinML APIs.

I get the following error:

Unspecified error

Type Error: Type (map(string,tensor(float))) of output arg (loss) of node (ZipMap) does not match expected type (seq(map(string,tensor(float)))).

The updated WinML APIs only work with ONNX models that are v1.2. What version is exported by Custom Vision? Just a guess that version requirements may be the cause of the issue.

Custom Vision service was just updated to allow the download of ONNX 1.2 models via the portal. This solved the issue using the new model version.
