class penzai.nn.basic_ops.Elementwise[source]#

Bases: Layer

A layer that runs an elementwise operation on its NamedArray argument.

The function is treated as a static object with no parameters, and automatically maps its argument over named axes of its input. It is useful for applying activation functions or other elementwise operations.

Variables:

fn (Callable[[Any], Any]) – The function to call.

tree_flatten_with_keys()

Flattens this tree node with keys.

tree_unflatten(aux_data, children)

Unflattens this tree node.
