Hi,
I’m rather new to acados and recently I’m trying to translate my already-running code written with casadi opti stack into acados (python interface). I haven’t so far get my code successfully running in acados yet due to a reported error of stat residual to be nan, all other residuals seem fine. I was just wondering what could be the source of my error and where should I be looking at to resolve it?\
Thanks,
