I want to have a function that accepts [1+2j] and np.array([1.j], dtype=np.complex128). I tried:

fn evaluate_complex_flat<'py>(
        &mut self,
        py: Python<'py>,
        inputs: PyArrayLike1<'py, Complex64, TypeMustMatch>,
    )

but I get:

error[E0277]: the trait bound `PyArrayLike<'_, num_complex::Complex<f64>, Dim<[usize; 1]>>: PyFunctionArgument<'_, '_, false>` is not satisfied
     --> src/api/python.rs:12195:17

Make sure you have enabled pyo3s "num-complex" feature. With that feature enabled this works for me.
