How to preprocess custom data sets?

[CHDTevior]

Very interesting work! I tried the sample combinations you provided and they worked amazingly, but I tried some more complex models, such as the demon hunter wearing a windbreaker, and the weight binding was not good. I looked at the datasets of the attached clothes you mentioned and found that my custom model might be quite different from them, so I want to try to organize the data myself to try training. Can you tell me what preprocessing work should be done? 我可以用中文交流
