But if we interrupted the engine during the first epoch, we would not have epoch_length.

We can relax the constraint that the both max_epochs and max_iters could not have values.

According to state_dict this should never happen.

I think we can't because the relationship between epoch and iteration becomes invalid then. By the way in the case epoch_length is changed, we could reinitialize the state (with epoch and iteration zero along with a message to the user) as well.
