Python – tensorflow.DeviceSpec.replace()

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。

replace()用于覆盖DeviceSpec对象的规范并获得新的对象。

语法:
tensorflow.DeviceSpec.replace(**kwargs)

参数:

• **kwargs：该方法接受DeviceSpec构造函数接受的所有参数。

返回：它返回一个DeviceSpec对象。

示例 1:

# Importing the library
import tensorflow as tf

# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", replica = 5)

# Printing the DeviceSpec 
print('Device Spec: ', device_spec.to_string())

# Getting new DeviceSpec object
new_device_spec = device_spec.replace(job = "gfg2")

# Printing the result
print('New Device Spec: ', new_device_spec.to_string())

输出:

Device Spec: /job:gfg/replica:5
New Device Spec: /job:gfg2/replica:5

示例 2:

# Importing the library
import tensorflow as tf

# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", replica = 5)

# Printing the DeviceSpec 
print('Device Spec: ', device_spec.to_string())

# Getting new DeviceSpec object
new_device_spec = device_spec.replace(job = "gfg2", device_type = "CPU")

# Printing the result
print('New Device Spec: ', new_device_spec.to_string())

输出:

Device Spec: /job:gfg/replica:5
New Device Spec: /job:gfg2/replica:5/device:CPU:*
