from __future__ imports must occur at the beginning of the file

In this document:
https://www.paddlepaddle.org.cn/documentation/docs/zh/beginners_guide/basics/image_classification/index.html
See this section of codes:

The line of from __future__ import print_function should be above all other imports. Otherwise will encounter a "from future imports must occur at the beginning of the file" error.
