Python – tensorflow.DeviceSpec.from_string()

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。

from_string用于从字符串生成 DeviceSpec。

Syntax: tensorflow.DeviceSpec.from_string( spec )

Parameters:

• spec: It is a string of the form  /job:/replica:/task:/device:CPU: or /job:/replica:/task:/device:GPU with all entries being optional.

Returns: It returns a DeviceSpec object generated by the string.

示例 1：

Python3

# Importing the library
import tensorflow as tf
  
# Formatting the string
spec = '/job:gfg / replica:1 / task:2'
  
# Initializing Device Specification
device_spec = tf.DeviceSpec.from_string(spec)
  
# Printing the DeviceSpec object
print('Device Spec: ', device_spec)

输出：

Device Spec:  

示例 2：

Python3

# Importing the library
import tensorflow as tf
  
# Formatting the string
spec = '/job:gfg / replica:2 / task:3'
  
# Initializing Device Specification
device_spec = tf.DeviceSpec.from_string(spec)
  
# Printing the DeviceSpec object
print('Device Spec: ', device_spec)

输出：

Device Spec:
