範例1：

Python3

# Importing the library 
import tensorflow as tf 
  
# Initializing Device Specification 
device_spec = tf.DeviceSpec(job ="gfg", device_type ="CPU", device_index = 0) 
  
# Printing the DeviceSpec object 
print('Device Spec:', device_spec) 
  
# Getting device index 
device_index = device_spec.device_index 
  
# Printing the result 
print('Device Index:', device_index)

輸出：


Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba96aee8>
Device Index: 0

範例2：

Python3

# Importing the library 
import tensorflow as tf 
  
# Initializing Device Specification 
device_spec = tf.DeviceSpec(job ="gfg", device_type ="CPU", device_index = 1) 
  
# Printing the DeviceSpec object 
print('Device Spec:', device_spec) 
  
# Getting device index 
device_index = device_spec.device_index 
  
# Printing the result 
print('Device Index:', device_index)

輸出：


Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba97f048>
Device Index: 1
