TensorFlow數值加減-認識Variable

tensorflow教程順序有點亂,其實這個應該放在第二篇的,大夥湊合看吧^_^

硬體:NVIDIA-GTX1080

軟體:Windows7、python3.6.5、tensorflow-gpu-1.4.0

一、基礎知識

當tf定義variable時,需要在session定義之後初始化一次!

二、程式碼展示

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.global_variables_initializer() #must have if define variable

with tf.Session() as sess:
    sess.run(init) #must have if define session
    for i in range(3):
        sess.run(update)
        print(sess.run(state))

三、結果展示
