The current ODE solver odeint is inflexible and suffers from problem of stiffness as explained here in some cases.
It is better to upgrade to ODE solver object-oriented ode, as it is more flexible and allows to set various options.

研究方向
Locate the current usage of odeint in the codebase (likely in the main solver module). Replace calls with the ode class, ensuring to set appropriate options like method and atol/rtol. Verify that results match after upgrade using existing tests. Check comments for any additional requirements from maintainers.
