Python tensorflow.DeviceSpec.task属性用法及代码示例

TensorFlow是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。

task用于获取DeviceSpec的任务索引。

用法：tensorflow.DeviceSpec.task

返回值：它返回DeviceSpec的任务索引

范例1：

Python3

# Importing the library 
import tensorflow as tf 
  
# Initializing Device Specification 
device_spec = tf.DeviceSpec(job ="gfg2", replica = 5, device_type ="GPU", device_index = 1) 
  
# Printing the DeviceSpec object 
print('Device Spec:', device_spec) 
  
# Getting task index 
task = device_spec.task 
  
# Printing the result 
print('Task Index:', task)

输出：

Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba981d08>
Task Index: None

范例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) 
  
# Printing the DeviceSpec object 
print('Device Spec:', device_spec) 
  
# Getting task index 
task = device_spec.task 
  
# Printing the result 
print('Task Index:', task)

输出：

Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba91a708>
Task Index: 2
