1. tensorflow demo

 

import tensorflow as tf
 
 
# 定义一个变量
  
t = tf.Variable(1,name='t')
  
# 初始化变量

sess = tf.Session()
 
sess.run(tf.global_variables_initializer())
 
# 打印当前值
 
sess.run(t)
 
# 保存当前值
 
saver = tf.train.Saver([t])
 
saver.save(sess,'/tmp/t.chpt',global_step=0)
 
 
# 修改值
 
sess.run(tf.assign_add(t,2))
 
 
# 恢复
saver.restore(sess,'/tmp/t.chpt-0')
