常量的四则运算

 import tensorflow as tf

 data1 = tf.constant(2)
 data2 = tf.constant(10)
 dataAdd=tf.add(data1,data2)
 dataSub = tf.subtract(data1,data2)
 dataMul = tf.multiply(data1,data2)
 dataDiv = tf.divide(data1,data2)
  with tf.Session() as sess:
      print(sess.run(dataAdd))
     print(sess.run(dataSub))
     print(sess.run(dataMul))
     print(sess.run(dataDiv))

常量和变量的的四则运算

 import tensorflow as tf
 data1 = tf.constant(2)
 data2 = tf.Variable(6)
 dataAdd=tf.add(data1,data2)
 dataSub = tf.subtract(data1,data2)
 dataMul = tf.multiply(data1,data2)
 dataDiv = tf.divide(data1,data2)
 init = tf.global_variables_initializer()
 with tf.Session() as sess:
     sess.run(init)
     print(sess.run(dataAdd))
     print(sess.run(dataSub))
     print(sess.run(dataMul))
     print(sess.run(dataDiv))
