- MNIST 데이터셋 불러오는 소스 코드 

https://github.com/tensorflow/tensorflow/blob/master/tensorflow/examples/tutorials/mnist/input_data.py

- 글자 이미지 png 파일로 저장하는 코드

import sys import input_data import numpy as np import matplotlib matplotlib.use('Agg') # Must be before importing matplotlib.pyplot or pylab! import matplotlib.pyplot as plt sys.path.append("/root/work/") mnist = input_data.read_data_sets("data_in/", one_hot = True) print mnist.train.labels[1] print mnist.train.images[1] for idx in range(1,10): # show mnist arr = np.array(mnist.train.images[idx]) arr.shape = (28,28) fig = plt.figure() plt.imshow(arr) for numIdx in range(0,10): if mnist.train.labels[idx][numIdx] != 0: print numIdx break figPath = './data_out/mnist%s_%s.png' % (idx, numIdx) fig.savefig(figPath)

- 결과 (mnist1_3.png)
