为了收集训练数据，做了一个网页。用户选择喜欢的脸，后台会将用户的选择（标记）写到数据库。

To get training data, I have designed a website.

The user chooses the face they like, the back-end will record choices into database.

I wil display the picture by simple random sampling with replacement(which has not been realised yet).

This little project is mainly based on Flask.
