"""This is a very limited feature training loop useful for interactive debugging.
|
||
|
|
|
||
|
|
It is not intended for actual model tranining (it is not fast, doesn't compile the model).
|
||
|
|
It does not support checkpointing.
|
||
|
|
|
||
|
|
suggested use:

from tml.core import debug_training_loop

debug_training_loop.train(...)
