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.

Converting a PySpark dataframe to an array


In order to form the building blocks of the neural network, the PySpark dataframe must be converted into an array. Python has a very powerful library, numpy, that makes working with arrays simple.

Getting ready

The numpy library should be already available with the installation of the anaconda3 Python package. However, if for some reason the numpy library is not available, it can be installed using the following command at the terminal:

pip install or sudo pip install will confirm whether the requirements are already satisfied by using the requested library:

import numpy as np

How to do it...

This section walks through the steps to convert the dataframe into an array:

  1. View the data collected from the dataframe using the following script:
df.select("height", "weight", "gender").collect()
  1. Store the values from the collection into an array called data_array using the following script:
data_array =  np.array(df.select("height", "weight", "gender").collect())
  1. Execute...
