解决问题
read_data_sets (from tensorflow.contrib.learn.python.learn.datasets.mnist) is deprecated and will be removed in a future version.
Instructions for updating:
Please use alternatives such as official/mnist/dataset.py from tensorflow/models.
解决思路
read_data_set（来自tensorflow.contrib.learn.python.learn.data sets.mnist）已弃用，将在将来的版本中删除。
解决方法
更新说明：使用tensorflow/models中的official/mnist/dataset.py等备选方案。
将
from tensorflow.examples.tutorials.mnist import input_data
改为
from tensorflow.contrib.learn.python.learn.datasets.mnist import read_data_sets
哈哈，大功告成！
