WIP Could Baidu provide script to transform normal model to fake QAT model(QAT2.0). I will add link to the document. @juncaipeng Also it seems this doc is the only doc in PaddlePaddle about QAT, do you think it is proper to write more details on how to generate correct fake QAT models. Like in Tensorflow QAT doc, I will not paste link, but you can found it by searching.
