问Mnist数据图像和标签不匹配

EN

import matplotlib.pyplot as plt
from tensorflow.examples.tutorials.mnist import      input_data
import tensorflow as tf

mndata = input_data.read_data_sets("MNIST_data/", one_hot=True)

images_train=mndata.train.images    # training set
labels_train=mndata.train.labels    
images_test=mndata.test.images     # testing set
labels_test=mndata.test.labels

##### Testing single image to network

train_index=4

image = images_train[train_index]
label = labels_train[train_index]

plt.imshow(image.reshape(28,28))
plt.show()  
print('label',label)
