# torch.jit.unused

torch.jit.unused(fn)

  This decorator indicates to the compiler that a function or method should be ignored and replaced with the raising of an exception. This allows you to leave code in your model that is not yet TorchScript compatible and still export your model.

  > Example (using `@torch.jit.unused` on a method):

  >     import torch
  >     import torch.nn as nn

  >     class MyModule(nn.Module):
  >         def __init__(self, use_memory_efficient):
  >             super().__init__()
  >             self.use_memory_efficient = use_memory_efficient

  >         @torch.jit.unused
  >         def memory_efficient(self, x):
  >             import pdb
  >             pdb.set_trace()
  >             return x + 10

  >         def forward(self, x):
  >             # Use not-yet-scriptable memory efficient mode
  >             if self.use_memory_efficient:
  >                 return self.memory_efficient(x)
  >             else:
  >                 return x + 10

  >     m = torch.jit.script(MyModule(use_memory_efficient=False))
  >     m.save("m.pt")

  >     m = torch.jit.script(MyModule(use_memory_efficient=True))
  >     # exception raised
  >     m(torch.rand(100))
