This is a gRPC-level error for an application-level (TensorFlow-level) error; something the TensorFlow folks *might* want to do is catch this in your client-side code and, by raising a TensorFlow-level exception instead, make it look more TensorFlow-y and less gRPC-y. Then again it may not be worth it, since it's describing a programming mistake and programming mistakes should be fixed rather than made to look pretty.

I think the error you're seeing is server-side TensorFlow code telling you that you've made a TensorFlow-level mistake and trying to describe the mistake to you (although the status details string it's giving you is pretty short). -Nathaniel -- You received this message because you are subscribed to the Google Groups "grpc.io" group.
