tensorflow讀取本地MNIST數據集
數據放入文件夾（不要解壓gz）：
>>> import tensorflow as tf
>>> from tensorflow.examples.tutorials.mnist import input_data
>>> MNIST_data =r'D:\tensorflow\mnist'
>>> mnist = input_data.read_data_sets(MNIST_data,one_hot=True)

WARNING:tensorflow:From d:\ProgramData\Anaconda3\lib\site-packages\tensorflow\contrib\learn\python\learn\datasets\mnist.py:267: extract_labels (from tensorflow.contrib.learn.python.learn.datasets.mnist) is deprecated and will be removed in a future version.
Instructions for updating:
Please use tf.data to implement this functionality.
