Scipy solve_ivp vs odeint

问题

I have a large system of differential equations I am trying to solve. I get the same results using scipy.odeint and scipy.solve_ivp, however the former is ~17 times faster in my case. I read that solve_ivp is recommended for initial value problems, but can't find more on why I can't use odeint (when it's giving me the same results).

Do I need to use solve_ivp when I am getting the same results as from odeint? When would I use one vs the other?

Thanks.
