In the monopod. py file under the /omsf/examples path, I couldn't find the definitions for importing casadi as cs cs.quad_form, cs.MXFunction, cs.ImplicitFunction, etc. At first, I thought it was a version issue with my casadi. I tried casadi 3.5.1, casadi 3.4.1, and casadi 3.3.1, but couldn't find the definitions for these functions.
