Python tensorflow.IndexedSlices.name屬性用法及代碼示例

TensorFlow是Google設計的開源Python庫，用於開發機器學習模型和深度學習神經網絡。

名稱用於查找索引切片的名稱。這僅在禁用急切執行時有效。

用法：tensorflow.IndexedSlices.name

範例1：在此示例中，啟用了急切執行，因此將引發AttribbuteError。

# Importing the library 
import tensorflow as tf 
  
# Initializing the input 
data = tf.constant([[1, 2, 3], [4, 5, 6]]) 
  
# Printing the input 
print('data:', data) 
  
# Calculating result 
res = tf.IndexedSlices(data, [0], 1) 
  
# Finding name 
name = res.name 
  
# Printing the result 
print('Name:', name)

輸出：

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

AttributeError:Tensor.name is meaningless when eager execution is enabled.

範例2：在此示例中，急切執行被禁用。

# Importing the library 
import tensorflow as tf 
  
# Initializing the input 
data = tf.constant([[1, 2, 3], [4, 5, 6]]) 
  
# Printing the input 
print('data:', data) 
  
# Calculating result 
res = tf.IndexedSlices(data, [0], 1) 
  
# Finding name 
name = res.name 
  
# Printing the result 
print('Name:', name)

輸出：

data: Tensor("Const_13:0", shape=(2, 3), dtype=int32)
Name: Const_13:0
