Useful for when you'd like to apply the same configuration arguments to all child modules that you wrap. A particularly important use case is wrapping large layers so that they get sharded (in-place) during initialization, to avoid running out of system memory. Large layers can indicate that they should be sharded via the ``wrap`` annotation and this context manager can provide the exact configuration for these nested instances. Usage:: with enable_wrap(wrapper_cls, **params): # Wraps layer in FSDP by default if within context self.l1 = wrap(torch.nn.Linear(5, 5)) Args: wrapper_cls: Class that `wrap` annotation will `wrap` modules with, such as `FullyShardedDataParallel`. **wrapper_kwargs: Configuration settings that will be passed to all ``wrap`` instances inside the context rNr3)_ConfigAutoWrap)rrr4s r'rrs6: { F  "6 "  # " "s3" 3 03wrap_overridesc [R(aB[Rce0[REUEn[ U[R40UD6$U$)a Annotate that a module should be wrapped. Annotated modules will only be wrapped if inside of an :func:`enable_wrap` context manager. This allows a module to be initialized both with and without a wrapper without code change. The class that this function wraps the passed in ``nn.Module`` with is the passed in ``wrapper_cls`` argument into ``enable_wrap``. Both ``enable_wrap`` and ``wrap`` can take in kwargs specifying how to construct the ``wrapper_cls`` instance. In the case of duplicate kwargs in ``enable_wrap`` and ``wrap``, the argument passed into ``wrap`` will be respected. Usage:: with enable_wrap(wrapper_cls=FSDP, **fsdp_config): # Wraps layer in FSDP by default if within context self.l1 = wrap(torch.nn.Linear(5, 5)) Args: module (nn.Module): module to wrap (if in :func:`enable_wrap` context) **wrap_overrides: configuration overrides that will take priority over the values provided by the :func:`enable_wrap` context )rin_autowrap_contextrr4_wrap)rrs r'rrs^2****666EO22EnE   ' '   Mr)c rUce[US5(a0UEUREnU"U40UD6$U"U40UD6$)N_wrap_overrides)hasattrr)rrr4 overridess r'rrsS  "" "v()) 9v8!7!78 6/Y// v ( ((r)auto_wrap_policyignored_paramsonly_wrap_childrenr4c ^UcS5eUcS5eUR5H.upxX;aM [U[[U55(aeM0 [ U4SjUR 555n UceU"USU S9(anSn UR5H/upX;aM [S UUUUTS.UD6up[X U 5 X- n M1 X- nU(dU"USUS9(a[X40UD6U 4$X 4$US4$![a Mf=f) a Wraps submodules of ``module`` for which ``auto_wrap_policy`` returns ``True`` with ``wrapper_cls``.
