The decorator verifies that the wrapped function does not modify parameter, buffer or sub-module fully-qualified names (FQN). 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): >>> 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() csJttjttjdfdd }tjttdfdd }||_|S)Nmodulereturncst}|jt|}t|ts&Jdt}|jt|}t|tsLJd|vr^j|vstJdjd|||jtt| }t|j dd}t|j dd} |g|Ri|} | dur|} t| } t| j dd} t| j dd} t| t j s,Jdt| ttttdd d }|t|t| |t|t| |t| t| | S) Nz+Distributed composable API states corruptedz-Distributed composable API registry corruptedzOEach distinct composable distributed API can only be applied to a module once. z3 has already been applied to the following module.
