下载MNIST报错，mnist = input_data.read_data_sets('MNIST_data', one_hot=True)报错

最近在看莫凡的视频，咦，出错了呀

from tensorflow.examples.tutorials.mnist import input_data

mnist=input_data.read_data_sets('MNIST_data',one_hot=True)

报错如下：

解决方法：

如图所示，先找到mnist.py

下载MNIST报错，mnist = input_data.read_data_sets('MNIST_data', one_hot=True)报错

然后进入mnist.py文件中进行修改如下：

下载MNIST报错，mnist = input_data.read_data_sets('MNIST_data', one_hot=True)报错

即：将

# CVDF mirror of http://yann.lecun.com/exdb/mnist/
DEFAULT_SOURCE_URL = 'https://storage.googleapis.com/cvdf-datasets/mnist/'

修改为：

# CVDF mirror of http://yann.lecun.com/exdb/mnist/
#DEFAULT_SOURCE_URL = 'https://storage.googleapis.com/cvdf-datasets/mnist/'
DEFAULT_SOURCE_URL = 'http://yann.lecun.com/exdb/mnist/'

小可爱记得修改完mnist.py文件之后保存一下呀~
