set_activation_checkpointing

torchtune.utils.set_activation_checkpointing(model: Module, auto_wrap_policy: Union[Set[Type], Callable[[Module, bool, int], bool]], **kwargs) → None

Utility to apply activation checkpointing to the passed-in model.

Parameters:

• model (nn.Module) – Model to apply activation checkpointing to.

• auto_wrap_policy (ACWrapPolicyType) – Policy to wrap module. This can either be a set of nn.Module types, in which case, modules of the specified type(s) will be wrapped individually with activation checkpointing, or a callable policy describing how to wrap the model with activation checkpointing. For more information on authoring custom policies, please see this tutorial: https://pytorch.org/tutorials/intermediate/FSDP_adavnced_tutorial.html#transformer-wrapping-policy.

• **kwargs – additional arguments to pass to torch.distributed activation checkpointing.
