Jitted

class penzai.toolshed.jit_wrapper.Jitted

Bases: Layer

Wraps a pure layer to run under JIT compliation.

The Jitted wrapper has the same behavior and input/output structure as the layer it wraps, but modifies __call__ so that every call is run under JIT compilation. Variables in the layer will be updated correctly using pz.variable_jit.

Since Jitted is an ordinary Layer, you can still inspect the contained layer and make modifications to it. This will automatically trigger a recompile, since the jax.jit call depends on the PyTree structure of the Jitted block.

Variables:

body (pz.nn.Layer) – The layer that should run under JIT compilation.
