Python tensorflow.DeviceSpec.__eq__()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。

__eq__()用於檢查兩個DeviceSpec對象的相等性。

用法：tensorflow.DeviceSpec.__eq__( other )

參數：

other:它是一個DeviceSpec對象。

返回值：如果DeviceSpec對象規範相同，則返回True，否則返回False。

範例1：

Python3

# Importing the library 
import tensorflow as tf 
  
# Initializing Device Specification 
device_spec = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="GPU", device_index = 1) 
device_spec2 = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="GPU", device_index = 1) 
  
# Printing the DeviceSpec object 
print('Device Spec:', device_spec.to_string()) 
print('Device Spec2:', device_spec2.to_string()) 
  
# Finding the result 
res = device_spec.__eq__(device_spec2) 
  
# Printing the result 
print('Res:', res)

輸出：


Device Spec: /job:gfg2/replica:5/task:2/device:GPU:1
Device Spec2: /job:gfg2/replica:5/task:2/device:GPU:1
Res: True

範例2：

Python3

# Importing the library 
import tensorflow as tf 
  
# Initializing Device Specification 
device_spec = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="GPU", device_index = 1) 
device_spec2 = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="CPU", device_index = 2) 
  
# Printing the DeviceSpec object 
print('Device Spec:', device_spec.to_string()) 
print('Device Spec2:', device_spec2.to_string()) 
  
# Finding the result 
res = device_spec.__eq__(device_spec2) 
  
# Printing the result 
print('Res:', res)

輸出：


Device Spec: /job:gfg2/replica:5/task:2/device:GPU:1
Device Spec2: /job:gfg2/replica:5/task:2/device:CPU:2
Res: False
