The only thing is the model file replacement?

[QingboKang]

As the author said "You only need to replace the "model.py" file with the one attached here and update other info(model name, dataset etc.) accordingly." But the code in https://github.com/weizheliu/People-Flows is for another totally different paper. Is anyone reproduce the code?
Because I saw only the SFCN implementation in the model file, nothing about the self-supervision.
Could anyone give some information? thanks
