thresholding. This thresholding method is unsuitable for latent-space diffusion models such as
Stable Diffusion.  
The SDE variant of DPMSolver and DPM-Solver++ is also supported, but only for the first and second-order solvers. This is a fast SDE solver for the reverse diffusion SDE. It is recommended to use the second-order `sde-dpmsolver++`.
