Python – tensorflow.guarantee_const()

TensorFlow 是由 Google 设计的开源Python库，用于开发机器学习模型和深度学习神经网络。

ensure_const ()用于确保 TensorFlow 运行时输入张量是恒定的。

Syntax: tensorflow.guarantee_const( input, name)

Parameters: 

• input: It is a Tensor.
• name(optional): It defines the name for the operation

Returns: It returns a Tensor same as input Tensor.

示例 1：

Python3

# Importing the library
import tensorflow as tf
 
# Initializing the Tensor
x = tf.guarantee_const(5)
 
# Printing the result
print("x: ", x)

输出：

x:  tf.Tensor(5, shape=(), dtype=int32)

示例 2：

Python3

# Importing the library
import tensorflow as tf
 
# Initializing the Tensor
x = tf.Variable(2.0, name ="x")
z = tf.Variable(4.0, name ="z")
 
# Using guarantee_const
y = tf.guarantee_const([x, z])
 
# Printing the result
print("y: ", y)

输出：

y:  tf.Tensor([2. 4.], shape=(2, ), dtype=float32)
