source

class espnet2.tts2.feats_extract.abs_feats_extract.AbsFeatsExtractDiscrete(*args, **kwargs)

Bases: Module, ABC

Parse the discrete token sequence into structured data format for predicting. E.g., (1) keep as sequence (2) resize as a matrix (3) multi-resolution …

Initializes internal Module state, shared by both nn.Module and ScriptModule.

abstract forward(input: Tensor, input_lengths: Tensor) → Tuple[Any, Dict]

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.
