DisabledDropout

class penzai.nn.dropout.DisabledDropout

Bases: Identity

A no-op layer taking the place of a disabled StochasticDropout layer.

This layer can be used to mark a location in a model where dropout could be applied, or where dropout was originally applied before disabling it. Its attributes are unused, except that they can be used to rebuild a StochasticDropout layer.

Variables:

• drop_rate (float) – Drop rate for the enabled (StochasticDropout) version of this layer.

• share_across_axes (tuple[str, ...]) – Shared axis names for the enabled (StochasticDropout) version of this layer.

Methods

__init__(drop_rate, share_across_axes)
enable()	Returns a stochastic, enabled version of this layer.

attributes_dict()	Constructs a dictionary with all of the fields in the class.
from_attributes(**field_values)	Directly instantiates a struct given all of its fields.
input_structure()	Returns the input structure of this layer.
key_for_field(field_name)	Generates a JAX PyTree key for a given field name.
output_structure()	Returns the output structure of this layer.
select()	Wraps this struct in a selection, enabling functional-style mutations.
