Thanks for your PR. Can you also maybe report the memory it helps in saving? |

With the some configs, without these modifications, I faced OOM with batch size = 1. After modification, I can run the test with batch size = 16. |

@leisuzz @sayakpaul great contribution thanks! I want to add these changes to the advanced flux script too, is this last part specifically helpful? since it happens after the weights are already uploaded/pushed to the hub

It actually depends on the limit of memory and the user's hardware, but it will clean some memory usages for sure
