Question about Non-IID settings

[Fruit0218]

Hello author, I am currently testing your code, but I am curious to know where in the code files the non-iid setting implemented in the ./data/cityscapes/data/ folder is achieved? Specifically, where are those .json files generated from? I seem unable to find the relevant functions in your code files.
