Python – tensorflow.DeviceSpec.replica 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。

replica用于获取 DeviceSpec 的副本索引。

Syntax: tensorflow.DeviceSpec.replica

Returns: It returns the replica index of the DeviceSpec.

示例 1：

Python3

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

输出：

Device Spec:  
Replica:  None

示例 2：

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 replica index
replica = device_spec.replica
  
# Printing the result
print('Replica: ', replica)

输出：

Device Spec:  
Replica:  5
