TensorFlow基礎3——tf.Variable()和tf.constant()

tf.Variable()生成變量

tf.constant()生成常量

變量需要初始化：

init = tf.initialize_all_variables()

sess.run(init)

import tensorflow as tf 

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

new_value = tf.add(state,one)
update = tf.assign(state,new_value)

init = tf.initialize_all_variables()

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