[theano]入门-文件读写

文件读写涉及到cPickle这个包。基本的流程在代码中有表述，但是教程中说加一段代码叫做：protocol=cPickle.HIGHEST_PROTOCOL会使得效率大增

 

#!/usr/bin/env python
# coding=utf-8
import cPickle
f=file('obj.txt','wb')
my_obj=3
cPickle.dump(my_obj,f,protocol=cPickle.HIGHEST_PROTOCOL)
f.close()

f=file('obj.txt','rb')
load_obj=cPickle.load(f)
f.close()
print load_obj

obj1=1
obj2=2
obj3=3
f=file('obj.txt','wb')


for obj in [obj1,obj2,obj3]:
    cPickle.dump(obj, f,protocol=cPickle.HIGHEST_PROTOCOL)
f.close()

f=file('obj.txt','rb')

obj=[] 
for i in range(3):
    obj.append(cPickle.load(f))
f.close()

print obj
