ConstrainSharding

class penzai.toolshed.sharding_util.ConstrainSharding

Bases: Layer

A layer that constrains the sharding of a tree of arrays.

Note: Defined using the experimental v2 API, but compatible with both v1 and v2 APIs (due to not having any parameters or state variables).

Variables:

sharding (PyTreeOfShardings) – A PyTree of shardings. The PyTree structure must match the structure of the tree of arrays that will be passed to this layer.

Methods

__init__(sharding)
__call__(tree, **_unused_side_inputs)
