latent diffusion deterministic forward pass

[TerryMelody]

In ddim.py, is there any implementation of this todo part: deterministic forward pass?
if mask is not None:
assert x0 is not None
img_orig = self.model.q_sample(x0, ts) # TODO: deterministic forward pass?
img = img_orig * mask + (1. - mask) * img
