Hi,
when i try to run the code, it comes out some errors as follows:

It seems that there are some conflicts in numba version, and my version only support a homogeneous sequence, can you give a list of your python and numba version?
Hi,
I am using a python environment named Firedrake (PDE solver) together with another libraries called pygmsh to implement a dynamical system inside the function f(x,u). When I try to run the code, it appears that one of my utility functions has an incompatibility with Numba, even though it doesn't use Numba at all.
Is there any way to make Numba invoked by ilqr ignore my functions?
