evious discrete timestep in the diffusion chain.


sample (torch.FloatTensor) —
current instance of sample being created by diffusion process.


order (int) — the order of UniP at this step, also the p in UniPC-p.


Returns

torch.FloatTensor



the sample tensor at the previous timestep.


One step for the UniP (B(h) version). Alternatively, self.solver_p is used if is specified.
