tensorflow-算术运算和函数间的关系

import tensorflow as tf

a = tf.Variable(3.0)

b = tf.constant(4.2)

c = tf.add(a,b)

#张量间的普通加法也会转换成tf.add这种节点

d = a+b

e = tf.mul(a,b)

#张量间的普通乘法也会转换成tf.mul这种节点

f = a*b

init = tf.global_variables_initializer()

with tf.Session() as sess:

    sess.run(init)

    print(c)

    print(sess.run(c))

    print(d)

    print(sess.run(d))

    print(e)

    print(sess.run(e))

    print(f)

    print(sess.run(f))
