python序列化（数据本地存放持久性存储）和反序列化

http://blog.csdn.net/uestcyao/article/details/7874817

#读取图片并存储为矩阵
from scipy.misc import imread
im = imread("/Users/NaCl/Documents/GitHub/test.png")

#将读取到的矩阵数据序列化、即进行持久性存储
from numpy import *
import pickle

with open('test.pickle', 'wb') as f:
    pickle.dump(im, f)   

#将数据进行反序列化
with open('/Users/NaCl/Documents/GitHub/test.pickle', 'rb') as f:
    f = pickle.load(f)
    print type(f)
    print f.shape
