Wouldn’t we want to put these lines inside an if statement? The prediction loop still doesn’t work with these outputs right?

Nope it does now since the functions that detach/concat etc. all work on nested list/tuples of tensors :-)

What does this PR do?
This PR tries to limit the access to
model.configinTrainerto the minimum so that it works with regular PyTorch modules (as long as they accept dict inputs and return loss first like our models). The most challenging part was the storing/restoring of thetotal_flos, which I moved to the newly createdTrainerState. It should work as before and be saved along the rest of the training state.
