import os
import tensorflow as tf
os.environ['TF_CPP_MIN_LOG_LEVEL']='2'

#创建常量和变量
state = tf.Variable(0,name='counter')
one = tf.constant(1)

#搭建模型
new_value = tf.add(state,one)
update = tf.assign(state,new_value)

#变量初始化
init = tf.initialize_all_variables()

#训练
with tf.Session() as sess:
    sess.run(init)
    for _ in range(3):
        sess.run(update)
        print(state)
        #此处必须指向state的指针，单纯打印print(state),返回state的格式==>
        print(sess.run(state))

结果为：
