I'm not super fond of having this done automatically. It should be in a
free_memory
method of theTrainer
(or a name you like better) that is explicitly called by the user between training and evaluation IMO.This is also useful beyond deepspeed.

These are 2 different things.
train
:transformers/src/transformers/trainer.py
Lines 765 to 771 in 22a32cf
so this PR explicitly cleans these up at the end of
train
- this is completely opaque. A user had no way to init those explicitly and thus has no need to do anything special.As you pointed out this would be useful to the user, but it's a different situation, so let's solve it separately?

Ah yes, it's true that in this case they are instantiated inside the
train
method so this makes sense.
