Difficulties loading adversarially trained models

[lukasShuber]

I didn't succeed in loading the adversarially trained models. run_evaluation results in the following error:

HTTP Error 403: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Any idea how to fix this?

Thanks for pointing this out. This was caused by the external repository from which we obtained the adversarially trained models, and observed/fixed in https://github.com/microsoft/robust-models-transfer/issues/12 on their end. I updated the model URLs in commit 4131742 which resolves the issue.
