terminate called after throwing an instance of 'google::protobuf::FatalException'
Loading the iwslt2017-en-nl config of iwslt2017 works fine on my side. 
Maybe you can open an issue on transformers as well ? And also add more details about your environment (OS, python version, version of transformers and datasets etc.) closing now, figured out this is because the max length of decoder was set smaller than the input_dimensions. thanks 
Hi
