Tensorflow机器学习3 Variable用法

import tensorflow as tf

#P11 例子 https://www.bilibili.com/video/av16001891/?p=11

state = tf.Variable(0,name='counter')
print(state.name)
one = tf.constant(1)

new_value = tf.add(state,one)
#把new_value的值赋值给state
update = tf.assign(state,new_value)

#如果定义了variable一定要初始化
init = tf.global_variables_initializer()

with tf.Session() as sess:
    sess.run(init)
    for _ in range(3):
        sess.run(update)
        print(sess.run(state))

运行结果：

counter:0
1
2
3
