create_jax_discipline_from_discipline(
    discipline: Discipline, *args: Any, **kwargs: Any
) -> JAXDiscipline

Create a JAXDiscipline from a discipline using JAX instead of NumPy and SciPy.

It will use the same input variables, the same output variables and the same default input values.

Parameters:

  • discipline (Discipline) –

    The discipline using JAX instead of NumPy and SciPy.

  • *args (Any, default: () ) –

    The positional arguments of JAXDiscipline, except function, input_names, output_names and default_inputs.

  • **kwargs (Any, default: {} ) –

    The keyword arguments of JAXDiscipline.

Returns:

Warning

JAX's automatic differentiation works with Python control flow and logical operators. Using control flow and logical operators with jit (see compile_jit) is more complicated. If you have any difficulties, you can have a look at https://docs.jax.dev/en/latest/control-flow.html.
