pe slightly affects
the sample quality, especially for small number of steps. We empirically find that midpoint solvers are
slightly better, so we recommend to use the midpoint type.


lower_order_final (bool, default True) —
whether to use lower-order solvers in the final steps. Only valid for < 15 inference steps. We empirically
find this trick can stabilize the sampling of DPM-Solver for steps < 15, especially for steps <= 10.
