espnet2.asr.frontend.cnn.Dim1LayerNorm

source

class espnet2.asr.frontend.cnn.Dim1LayerNorm(normalized_shape, eps=1e-05, elementwise_affine=True, bias=True)

Bases: Module

LayerNorm on middle dim.

It assumes the input is shape B, D, T to avoid transposing. Faster than TransposedLayerNorm, but may lead to minor numerical differences.

forward(x)

Defines the computation performed at every call.

Should be overridden by all subclasses.

NOTE

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
