Very nice work!
A little question is why the time of studnet is "t - self.time_scale", i think it may be "t"?
Link:

ProDiff/modules/ProDiff/model/ProDiff.py

Line 172 in 1d199bc

    
           x_t_prev_pred = self.q_posterior_sample(x_pred, x_t, t - self.time_scale) * nonpadding # [-1, 1] p(x_t-1|x_t,x_0,t)

Because we need a teacher to distill the knowledge to a student, which have different time scales (T=2 vs. T=4)
