I am new to diffuser lib and accelerator , in the example/train_text_to_image.py
Line 700 in c13dbd5
I see the main_process_first is called, I am confused about this. Is it necessary to use it? why should the main process do the operation first?
Addtionally, I see you pass the seed to the shuffle function, so every process can get the same seed value which can make sure each of them gets the same dataset?
Thanks a lot！
