 step sizes in the noise schedule during the sampling process. If True,
the sigmas are determined according to a sequence of noise levels {σi}.   use_lu_lambdas (bool, optional, defaults to False) —
Whether to use the uniform-logSNR for step sizes proposed by Lu’s DPM-Solver in the noise schedule during
the sampling process. If True, the sigmas and time steps are determined according to a sequence of
lambda(t).   final_sigmas_type (str, default
