Hi! I am interested in implementing DDIM sampling for the LION model. However, I wish to know more details regarding how you sampled LION model through DDIM sampling. As I do not know which parameter values were used for DDIM sampling (except number of steps, which is 25 as stated in the paper), I have used the same values for parameter values of DDIMScheduler. Is there any part that I need to modify here? or is this identical setting as introduced in the LION paper?

if you want to change the number of step in sampling, you could change here: https://github.com/nv-tlabs/LION/blob/main/models/lion.py#L39 change the numebr 1000 to 25
