Python – tensorflow.DeviceSpec.device_index 属性

TensorFlow 是由 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。

device_index用于获取 DeviceSpec 的设备索引。

Syntax: tensorflow.DeviceSpec.device_index

Returns: It returns the device index.

示例 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)

输出：

Device Spec:  
Device Index:  0

示例 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)

输出：

Device Spec:  
Device Index:  1
