WebFeb 13, 2024 · Turns out it's the statement if cur_step % configs.val_steps == 0 that causes the problem. The size of dataloader differs slightly for different GPUs, leading to different configs.val_steps for different GPUs. So some GPUs jump into the if statement while others don't. Unify configs.val_steps for all GPUs, and the problem is solved. – Zhang Yu
