[Dian-Yi]

thansk yout works. i am new in this project. i read yout full process and have some problems.

1. You provided some pretrained models, do i need train ? i want to just simply test this project.
2. if i need train, when i change the target videos, do i need retrain the models?
3. if i need train the model, do i just train pose2vid network and face enhancement network? and run" make_gif.py", will get the results?
