Python – tensorflow.get_static_value()

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。

get_static_value()用于计算 Tensor 的静态值。如果无法计算静态值，它将返回 None。

Syntax: tensorflow.get_static_value(tensor, partial)

Parameters:

• tensor: It is the input Tensor whose static value need to be calculated.
• partial: Either True of False with default value set to False. It is set to True to allow returned array to have partially calculated values.

Returns: It returns a numpy ndarray that contains the calculated result.

示例 1：

Python3

# Importing the library
import tensorflow as tf
 
# Initializing the input
data = tf.constant([[1, 2, 3], [3, 4, 5], [5, 6, 7]])
 
# Printing the input
print('data: ',data)
 
# Calculating result
res = tf.get_static_value(data)
 
# Printing the result
print('res: ',res)

输出：

data:  tf.Tensor(
[[1 2 3]
 [3 4 5]
 [5 6 7]], shape=(3, 3), dtype=int32)
res:  [[1 2 3]
 [3 4 5]
 [5 6 7]]

示例 2：

Python3

# Importing the library
import tensorflow as tf
 
# Initializing the input
data = tf.Variable([[1, 2, 3], [3, 4, 5], [5, 6, 7]])
 
# Printing the input
print('data: ',data)
 
# Calculating result
res = tf.get_static_value(data)
 
# Printing the result
print('res: ',res)

输出：

data:  
res:  None
