Python–张量流。设备规格任务属性

原文:https://www.geesforgeks.org/python-tensorflow-device spec-task-attribute/

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。

任务用于获取 DeviceSpec 的任务索引。

语法:张量流。DeviceSpec.task

返回:返回 DeviceSpec 的任务索引

例 1:

蟒蛇 3

# 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

例 2:

蟒蛇 3

# 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
