常量的四则运算

 1 import tensorflow as tf
 2 
 3 data1 = tf.constant(2)
 4 data2 = tf.constant(10)
 5 dataAdd=tf.add(data1,data2)
 6 dataSub = tf.subtract(data1,data2)
 7 dataMul = tf.multiply(data1,data2)
 8 dataDiv = tf.divide(data1,data2)
 9 10 with tf.Session() as sess:
11 12     print(sess.run(dataAdd))
13     print(sess.run(dataSub))
14     print(sess.run(dataMul))
15     print(sess.run(dataDiv))

常量和变量的的四则运算

 1 import tensorflow as tf
 2 data1 = tf.constant(2)
 3 data2 = tf.Variable(6)
 4 dataAdd=tf.add(data1,data2)
 5 dataSub = tf.subtract(data1,data2)
 6 dataMul = tf.multiply(data1,data2)
 7 dataDiv = tf.divide(data1,data2)
 8 init = tf.global_variables_initializer()
 9 with tf.Session() as sess:
10     sess.run(init)
11     print(sess.run(dataAdd))
12     print(sess.run(dataSub))
13     print(sess.run(dataMul))
14     print(sess.run(dataDiv))
