Jumpy

Jumpy is a common backend for JAX or numpy:

• A jumpy function returns a JAX outputs if given a JAX inputs
• A jumpy function returns a JAX outputs if jitted
• Otherwise a jumpy function returns numpy outputs

Jumpy lets you write framework agnostic code that is easy to debug by running as raw numpy, but is just as performant as JAX when jitted.
