Python – tensorflow.DeviceSpec.__eq__()

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。

__eq__()用于检查两个 DeviceSpec 对象的相等性。

Syntax: tensorflow.DeviceSpec.__eq__( other )

Parameters:

• other: It is a DeviceSpec object.

Returns: It returns True if DeviceSpec object specifications are same otherwise it returns False.

示例 1：

Python3

# Importing the library
import tensorflow as tf
  
# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="GPU", device_index = 1)
device_spec2 = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="GPU", device_index = 1)
  
# Printing the DeviceSpec object
print('Device Spec: ', device_spec.to_string())
print('Device Spec2: ', device_spec2.to_string())
  
# Finding the result
res = device_spec.__eq__(device_spec2)
  
# Printing the result
print('Res: ', res)

输出：

Device Spec:  /job:gfg2/replica:5/task:2/device:GPU:1
Device Spec2:  /job:gfg2/replica:5/task:2/device:GPU:1
Res:  True

示例 2：

Python3

# Importing the library
import tensorflow as tf
  
# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="GPU", device_index = 1)
device_spec2 = tf.DeviceSpec(job ="gfg2", replica = 5, task = 2, device_type ="CPU", device_index = 2)
  
# Printing the DeviceSpec object
print('Device Spec: ', device_spec.to_string())
print('Device Spec2: ', device_spec2.to_string())
  
# Finding the result
res = device_spec.__eq__(device_spec2)
  
# Printing the result
print('Res: ', res)

输出：

Device Spec:  /job:gfg2/replica:5/task:2/device:GPU:1
Device Spec2:  /job:gfg2/replica:5/task:2/device:CPU:2
Res:  False
