 # TensorFlow Sample: Getting Started with AI

TensorFlow is an open source machine learning platform used by developers and researchers to create intelligent systems. This sample shows how to get started with TensorFlow so you can begin building your own machine learning models.

## Introduction

This is a TensorFlow Sample that shows you how to get started with AI. It includes code and examples to get you started with TensorFlow.

## What is TensorFlow?

TensorFlow is an open-source software library for data analysis and machine learning. It was originally developed by Google Brain and is now used by a wide range of organizations, including Intel, Airbnb, Twitter, and NASA.

## TensorFlow Sample: Getting Started with AI

In this section, we’ll go over a TensorFlow sample that illustrates how to get started with AI. The sample we’ll be using is a simple implementation of Linear Regression. Linear Regression is amachine learning algorithm used to predict continuous values. For example, you could use Linear Regression to predict the price of a house given its size, number of bedrooms, etc.

## Installing TensorFlow

In order to install TensorFlow, you will need to have the following dependencies installed:

– pip
– six
– numpy
– protobuf
– wheel
– six>=1.10.0

## TensorFlow Basics

TensorFlow is a powerful tool for machine learning, but it can be difficult to get started. This sample will show you how to get started with TensorFlow, including how to install the software and run your first TensorFlow program.

## Creating a TensorFlow Graph

TensorFlow Graphs
TensorFlow automates the creation of computations that are represented as data flow graphs. In TensorFlow, data always flows from the graph inputs (nodes with no incoming edges) to the graph outputs (nodes with no outgoing edges). Each node in a TensorFlow graph represents a single computation, and each edge in a TensorFlow graph represents the flow of tensors between two nodes.

Creating a TensorFlow Graph
Computations in TensorFlow are represented by data flow graphs. A data flow graph is a directed acyclic graph (DAG) where each node represents an operation, and each edge represents the tensors that flow between two nodes. Nodes in a TensorFlow graph can take zero or more Tensors as inputs, and produce zero or more Tensors as outputs.

In addition to the nodes and edges that represent operations and tensorflows, every TensorFlow graph contains a GlobalStep counter. The GlobalStep counter is incremented every time a new batch of data is processed by the graph. The value of the GlobalStep counter can be used to keep track of training progress, early stopping criteria, etc.

## Running a TensorFlow Graph

TensorFlow graphs are powerful tools for implementing machine learning algorithms, but they can be a bit daunting for beginners. This tutorial will show you how to get started with TensorFlow by running a simple graph.

First, let’s import the TensorFlow module:

import tensorflow as tf

Next, we’ll create a TensorFlow graph. A graph consists of a set of nodes, where each node represents an operation. In this example, we’ll create a node that performs addition:

a = tf.constant(5)
b = tf.constant(10)
c = a + b

To run the graph, we need to create a TensorFlow session:

sess = tf.Session()
result = sess.run(c)

## Saving and Restoring a TensorFlow Model

In this section, you’ll learn how to save and restore a TensorFlow model. This is useful if you want to reuse a model that you have already trained, or if you want to deploy a model to production and don’t want to retrain it every time.

To save a model, you first need to create a TensorFlow session. This is where you manage the state of yourmodel. You’ll also need to create a saver object, which will store the variables of your model in disk so that you can restore them later.

Once you have created the session and saver objects, you can call the saver’s save() function, passing in the session and the path where you want to save the model. For example:

saver = tf.train.Saver()
saver.save(sess, ‘/path/to/save/model.ckpt’)

This will save the weights of your model in the checkpoint file /path/to/save/model.ckpt . You can then restore these weights by creating a new saver and calling its restore() function:

saver = tf.train.Saver()
saver.restore(sess, ‘/path/to/save/model.ckpt’)

## TensorFlow Estimators

TensorFlow Estimators are a high-level API that makes it easy to construct, train, and evaluate TensorFlow models. Estimators encapsulate the logic for training, evaluating, and predicting–making it easier to switch between different models.

If you’re just getting started with TensorFlow, we recommend checking out the Estimators quickstart. This will show you how to use an Estimator to train and evaluate a simple model on the Iris dataset.

## TensorFlow Hub

TensorFlow Hub is a library for the publication, discovery, and consumption of reusable parts of machine learning models. Models published on TF Hub can be reused in TensorFlow Lite and TensorFlow.js.

This guide shows you how to get started with TensorFlow Hub. You’ll learn how to use TF Hub to publish your own models, discover other people’s models, and use models in your own TensorFlow Lite and TensorFlow.js applications.
