lementation can be found at LuChengTHU/dpm-solver.  Tips It is recommended to set solver_order to 2 for guide sampling, and solver_order=3 for unconditional sampling. Dynamic thresholding from Imagen is supported, and for pixel-space
diffusion models, you can set both algorithm_type="dpmsolver++" and thresholding=True to use dynamic
thresholding. This thresholding method is unsuitable for latent-space diffusion models such as
Stable Diffusion.
