环境：tensorflow 代码如下 from tensorflow.examples.tutorials.mnist import input_data from scipy import misc import numpy as np import os mnist = input_data.read_data_sets('MNIST_data/',one_hot=True) result_path ='mnist_data\\train' def onehot2id(labels): return list(labels).index(1) if not os.path.exists(result_path): os.mkdir(result_path) labels_txt = open('train_labs.txt','w') for i in range(len(mnist.train.images)): img_vec = mnist.train.images[i,:] img_arr = np.reshape(img_vec,[28,28]) img_lab = mnist.train.labels[i,:] img_id = onehot2id(img_lab) labels_txt.write(str(i)+' '+str(img_id)+'\n') img_path = os.path.join(result_path,str(i)+'.png') misc.imsave(img_path,img_arr) 以
