TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.
device_index is used to get the device index of DeviceSpec.
Syntax: tensorflow.DeviceSpec.device_index
Returns: It returns the device index.
Example 1:
# Importing the library
import tensorflow as tf
# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", device_type ="CPU", device_index = 0)
# Printing the DeviceSpec object
print('Device Spec: ', device_spec)
# Getting device index
device_index = device_spec.device_index
# Printing the result
print('Device Index: ', device_index)
Output:
Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba96aee8> Device Index: 0
Example 2:
# Importing the library
import tensorflow as tf
# Initializing Device Specification
device_spec = tf.DeviceSpec(job ="gfg", device_type ="CPU", device_index = 1)
# Printing the DeviceSpec object
print('Device Spec: ', device_spec)
# Getting device index
device_index = device_spec.device_index
# Printing the result
print('Device Index: ', device_index)
Output:
Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fe5ba97f048> Device Index: 1
