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))
