Overview of this book

Organizations these days need to integrate popular big data tools such as Apache Spark with highly efficient deep learning libraries if they’re looking to gain faster and more powerful insights from their data. With this book, you’ll discover over 80 recipes to help you train fast, enterprise-grade, deep learning models on Apache Spark. Each recipe addresses a specific problem, and offers a proven, best-practice solution to difficulties encountered while implementing various deep learning algorithms in a distributed environment. The book follows a systematic approach, featuring a balance of theory and tips with best practice solutions to assist you with training different types of neural networks such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs). You’ll also have access to code written in TensorFlow and Keras that you can run on Spark to solve a variety of deep learning problems in computer vision and natural language processing (NLP), or tweak to tackle other problems encountered in deep learning. By the end of this book, you'll have the skills you need to train and deploy state-of-the-art deep learning models on Apache Spark.

Downloading 30 images each of Messi and Ronaldo


Before any classification of images can take place, we must first download images of our footballers from the web.

Getting ready

There are several add-ons to browsers that download images in bulk. Since Ubuntu comes pre-installed with Mozilla Firefox as a browser, we will use it as our browser of choice to install a bulk image downloader extension.

How to do it...

The following section explains how to download images in bulk. Take a look at these steps:

  1. Visit the following website for downloading and installing Firefox add-ons:

https://addons.mozilla.org/en-US/firefox/

  1. Search for and select the Download all Images add-on, as seen in the following screenshot:
  1. This will take us to the installation page. At which point, select Add to Firefox, as seen in the following screenshot:

  1. Confirm your installation, as this add-on will require permission to access your browser's download history, access your data for all websites, and send you notifications.
  2. Once...
