Python – tensorflow.DeviceSpec.replica Attribute

TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning  neural networks. 

replica is used to get the replica index of DeviceSpec.

Syntax: tensorflow.DeviceSpec.replica

Returns: It returns the replica index of the DeviceSpec.

Example 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)

Output:

Device Spec:  <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba981b88>
Replica:  None

Example 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)

Output:

Device Spec:  <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba981d08>
Replica:  5
