Python – Tensorflow math.add()方法
Tensorflow math.add()方法返回传入的a+b。该操作是在a和b的表示上进行的,该方法属于数学模块。
语法: tf.math.add(a, b, name=None)
参数
- a:这个参数应该是一个张量,并且是以下类型之一:bfloat16, half, float32, float64, uint8, int8, int16, int32, int64, complex64, complex128, string
- b:这也应该是一个张量,并且必须具有与a相同的类型。
- name: 这是一个可选的参数,这是操作的名称。
返回:它返回一个具有与输入a相同形状的张量。
让我们借助几个例子来看看这个概念。
示例 1:
# Importing the Tensorflow library
import tensorflow as tf
# A constant a and b
a = tf.constant(3)
b = tf.constant(6)
# Applying the math.add() function
# storing the result in 'c'
c = tf.math.add(a, b)
# Initiating a Tensorflow session
with tf.Session() as sess:
print("Input 1", a)
print(sess.run(a))
print("Input 2", b)
print(sess.run(b))
print("Output: ", c)
print(sess.run(c))
输出:
Input 1 Tensor("Const_79:0", shape=(), dtype=int32)
3
Input 2 Tensor("Const_80:0", shape=(), dtype=int32)
6
Output: Tensor("Add_1:0", shape=(), dtype=int32)

示例 2:
# Importing the Tensorflow library
import tensorflow as tf
# A constant a and b
a = tf.constant(u"This is ")
b = tf.constant(u"GeeksForGeeks")
# Applying the math.add() function
# storing the result in 'c'
c = tf.math.add(a, b)
# Initiating a Tensorflow session
with tf.Session() as sess:
print("Input 1", a)
print(sess.run(a))
print("Input 2", b)
print(sess.run(b))
print("Output: ", c)
print(sess.run(c))
输出:
Input 1 Tensor("Const_87:0", shape=(), dtype=string)
b'This is '
Input 2 Tensor("Const_88:0", shape=(), dtype=string)
b'GeeksForGeeks'
Output: Tensor("Add_5:0", shape=(), dtype=string)
b'This is GeeksForGeeks'
