flax.linen.with_logical_partitioning(fn, names, mesh=None, rules=None)[source]#

Wraps a function’s return value with LogicallyPartitioned.


kernel_init = with_logical_partitioning(
    nn.initializers.lecun_normal, (None, "data"))
partitioned_dense = nn.Dense(features, kernel_init=kernel_init)
  • fn – The function to be wrapped. Typically this is an initializer.

  • names – The logical axis passed to LogicallyPartitioned.

  • mesh – The mesh to use for the partitioning. If None, the global mesh resource is used if available.

  • rules – Optional logical to mesh rules use. If None, the global rules are used if available.


A function wrapping fn that will return an instance of LogicallyPartitioned.
