Python – tensorflow.DeviceSpec.task 属性

TensorFlow是谷歌设计的开源Python库，用于开发机器学习模型和深度学习神经网络。

task是用来获取DeviceSpec的任务索引。

语法: tensorflow.DeviceSpec.task

返回：它返回DeviceSpec的任务索引。

示例 1:

# 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

示例 2:

# 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
