to “learned” or “learned_range” for diffusion models that predict variance. If set, the model’s output
contains the predicted Gaussian variance.    DPMSolverSinglestepScheduler is a fast dedicated high-order solver for diffusion ODEs. This model inherits from SchedulerMixin and ConfigMixin. Check the superclass documentation for the generic
methods the library implements for all schedulers such as loading and saving.  convert_model_output  < so
