The decorator verifies that the decorated function does not modify fully-qualified names (FQNs) for parameters, buffers, or modules. The decorated function can return different module instances than the input modules; the FQN invariant will be enforced following the input order. When a function ``func`` is decorated by ``@contract()``, a ``.state(module: nn.Module)`` method will be installed to the decorated function. Then you can retrieve and modify the state on a module by calling ``func.state(module)``. Example:: >>> # xdoctest: +SKIP >>> import torch.nn as nn >>> >>> class MyModel(nn.Module): >>> def __init__(self) -> None: >>> super().__init__() >>> self.l1 = nn.Linear(10, 10) >>> self.l2 = nn.Linear(10, 10) >>> >>> def forward(self, x): >>> return self.l2(self.l1(x)) >>> >>> @contract() >>> def my_feature(module: nn.Module) -> nn.Module: >>> my_feature.state(module).some_state = "any value" >>> return module >>> >>> model = MyModel() >>> my_feature(model.l1) >>> assert my_feature.state(model.l1).some_state == "any value" >>> my_feature(model.l2) >>> model(torch.randn(2, 10)).sum().backward() ctdttjttjfdt tjffd }dtjdt t ffd }||_|S)Nmodulereturnc|}t|tjr|g}ntt |}}t }g}g}g} |D]f}t } t } |jjt| } t| tstd| |jjt| } t| tstd| | vsj| vrtdjd|| j|| jj||jt |j|jt |j!| jt |j#i|g|i|}||}t|tjr|g}ntt |}g}g}g}|D]z}|jt |j|jt |j!|jt |j#|t%| }t%|}||k7rtjd|d|ddt&t(d t&t(d t(fd }t+||D]=\}}|t |j-t |j-d ?t+||D]=\}}|t |j-t |j-d ?t+| |D]=\}}|t |j-t |j-d?|S)Nz-Distributed composable API states corrupted: z/Distributed composable API registry corrupted: zOEach distinct composable distributed API can only be applied to a module once. z3 has already been applied to the following module: zB should return the same number of modules as input modulesInputs: z modules Outputs: z modules orig_fqnsnew_fqns check_keyc||k(ryt|t|}}||z }||z }t|s t|rt|d|d|t|d|d|)NzVComposable distributed API implementations cannot modify FQNs.
