@Eurus-Holmes We tested this script using 8*A100 (80G VRAM). A single GPU cannot run this script.

However, what I tried was 8*H100 but still got OOM, I just used the same setting as examples/wanvideo/model_training/full/Wan2.2-S2V-14B.sh but changed examples/wanvideo/model_training/full/accelerate_config_14B.yaml num_machines to 8
