https://github.com/thuml/SimMTM/blob/main/SimMTM_Forecasting/scripts/pretrain/ECL_script/ECL.sh fails with GPU out of memory error in a A100 80GB.

RuntimeError: CUDA out of memory. Tried to allocate 13.26 GiB (GPU 0; 79.15 GiB total capacity; 60.37 GiB already allocated; 7.43 GiB free; 70.33 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation.
