Python - tensorflow.DeviceSpec.device_index Attribute Last Updated : 28 Jul, 2020 Comments Improve Suggest changes Like Article Like Report 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: Python3 # 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: Python3 # 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 Comment More info A aman neekhara Follow Improve Article Tags : Python Python-Tensorflow Python Tensorflow-math-functions Explore Python FundamentalsPython Introduction 3 min read Input and Output in Python 4 min read Python Variables 5 min read Python Operators 5 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 7 min read Python Functions 5 min read Recursion in Python 6 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 5 min read Python Tuples 4 min read Dictionaries in Python 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 2 min read Python MySQL 9 min read Python Packages 12 min read Python Modules 7 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 6 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 15+ min read StatsModel Library- Tutorial 4 min read Learning Model Building in Scikit-learn 8 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 7 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 7 min read Python | Build a REST API using Flask 3 min read How to Create a basic API using Django Rest Framework ? 4 min read Python PracticePython Quiz 3 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
