commend to use solver_order=2 for guided sampling, and solver_order=3 for unconditional sampling.
We also support the “dynamic thresholding” method in Imagen (https://arxiv.org/abs/2205.11487). For pixel-space
diffusion models, you can set both algorithm_type="dpmsolver++" and thresholding=True to use the dynamic
thresholding. Note that the thresholding method is unsuitable for latent-space diffusion models (such as
stable-diffusion).
