pass in zeros32?
() -> copy(x0)
Here you can pass a dummy function that takes in (rng, in_dims) and ignores them

PositiveDefinitecontainer wraps an underlying model and results in a model that returns a postive number whenever the input is nonzero (or not equal to a different point specified when defining the container). This is useful, among other applications, in neural Lyapunov applications.
