TF：TF定义两个变量相乘之placeholder先hold类似变量+feed_dict最后外界传入值—Jason niu

#TF：TF定义两个变量相乘之placeholder先hold类似变量+feed_dict最后外界传入值

import tensorflow as tf

input1 = tf.placeholder(tf.float32)  #TF一般只能处理float32的数据类型
input2 = tf.placeholder(tf.float32)  
#ouput = tf.mul(input1, input2) 
ouput = tf.multiply(input1, input2)       #定义两个变量相乘

with tf.Session() as sess:
    print(sess.run(ouput, feed_dict={input1: [1009.], input2: [2.]}))
