1.导入Keras相关模块
import numpy as np import pandas as pd from keras.utils import np_utils from keras.datasets import mnist
2.下载并验证数据
(X_train_image,y_train_label),(X_test_image,y_test_label) = mnist.load_data() print('train data=',len(X_train_image)) print('test data=',len(X_test_image)) Using TensorFlow backend. Downloading data from https://s3.amazonaws.com/img-datasets/mnist.npz train data= 60000 test data= 10000
