Been thinking about this one a lot lately - a few open questions I see:
-
In terms of implementation, does an auto-tuner have to be a wrapper around the composer library? In the event the call to
train_modelfails, I imagine we would have to pretty much just reinitialize everything in order to try again. -
What if the model's memory usage changes significantly over time? Some reasons this could happen include batch skips due to bad loss scaling, algorithms that increase the effective model size over time, and even checkpointing.
-
Auto-tuning will presumably take some time, and it would be ideal to not have to repeat this process every time a new run is launched. Is there a way we can persist discovered
grad_accumsettings across runs with our current infrastructure?
from composer.
