Summary:
InputTransform
s are required to betorch.nn.Module
subclasses but the base class does not inherit fromtorch.nn.Module
. This leads to type checker complaints when calling methods like.to(...)
, since it doesn't know that they areModule
s.This was originally motivated by the inheritance order of
Warp
transform, as we wantGPyTorchModule
methods to take precedence overtorch.nn.Module
. However, this not actually a concern since theGPyTorchModule
comes first in the MRO ofWarp
regardless of whetherInputTransform
inherits fromModule
(sinceGPyTorchModule
itself inherits fromModule
as well).This diff updates
InputTransform
to inherit fromModule
and removes the redundantModule
inheritance from subclasses.Differential Revision: D65338444
