Python–张量流。设备规格副本属性
原文:https://www . geesforgeks . org/python-tensorflow-device spec-replica-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。
副本用于获取 DeviceSpec 的副本索引。
语法:张量流。DeviceSpec.replica
返回:返回设备规格的副本索引。
例 1:
Python 3
# 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: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba981b88>
Replica: None
例 2:
Python 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 replica index
replica = device_spec.replica
# Printing the result
print('Replica: ', replica)
输出:
Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba981d08>
Replica: 5
