A list of the ``_FSDPState`` instances in the module tree rooted at ``module`` without any duplicates and following the ``module.modules()`` traversal order (which is assumed to be depth-first). 2. A corresponding list of the modules owning the states in the first list. For the wrapper code path, both returned lists are the same, each containing all ``FullyShardedDataParallel`` instances. For the composable code path, this returns a list of all composable state instances and a list of the corresponding fully sharded modules. See [Note: Fully Sharded Module]. NOTE: The traversal does not proceed into any module annotated by an incompatible API (e.g. ``replicate``). ) set collectionsdequepopleftaddrreversedrchildren appendleftrappend) r fsdp_states fsdp_modulesvisited_fsdp_statesvisited_modulesr submodule child_moduleoptional_states & r_get_fsdp_states_with_modulesr*0s&%'K$&L,/5'*eO +6*;*;VH*EE MMO I&9%% $T)*<*<*>%?@L2  .A0 :  %.*S  # #N 3   ~ .    *  $$rcZV^8dQhR\PR\\,/#r)r r rr)rs"rrr`s#RYY4 +;rc \V4wrV#)z*See :func:`_get_fsdp_states_with_modules`.)r*)r r#_s& r_get_fsdp_statesr.`s26:NK rcDV^8dQhR\PR\/#r)r r r)rs"rrrfs  bii D rcx\V4Uu.uFpVPfKVPNK! ppV#uupi)z{ Returns all ``FlatParamHandle`` s in the module tree rooted at ``module`` following the rules in :func:`_get_fsdp_state`. )r._handle)r fsdp_statehandless& r_get_fsdp_handlesr4fsF+622J     2  N s77) __doc__rtorch.nnr &torch.distributed._composable.contractr$torch.distributed.fsdp._common_utilsrrrr*r.r4rrr:s2@S&'-%` r
