I run the data and mask generation part and find this problem. It seems that It is when i load the model and sudddenly use a large part of memory. I wonder if you could give me some advice and solve it. Thanks a lot. @weijiawu

Same question. I only have 4 v100-16GB gpus, have you solved this problem?

Same problem here

@Liuhm0710 I was getting CUDA out of memory .Then i tried enabling low_resource = True in diffusion_step() function in ptp_utils.py file. Then this issue got removed
