Hands-On Python Deep Learning for the Web

By: Anubhav Singh, Sayak Paul

Overview of this book

When used effectively, deep learning techniques can help you develop intelligent web apps. In this book, you'll cover the latest tools and technological practices that are being used to implement deep learning in web development using Python. Starting with the fundamentals of machine learning, you'll focus on DL and the basics of neural networks, including common variants such as convolutional neural networks (CNNs). You'll learn how to integrate them into websites with the frontends of different standard web tech stacks. The book then helps you gain practical experience of developing a deep learning-enabled web app using Python libraries such as Django and Flask by creating RESTful APIs for custom models. Later, you'll explore how to set up a cloud environment for deep learning-based web deployments on Google Cloud and Amazon Web Services (AWS). Next, you'll learn how to use Microsoft's intelligent Emotion API, which can detect a person's emotions through a picture of their face. You'll also get to grips with deploying real-world websites, in addition to learning how to secure websites using reCAPTCHA and Cloudflare. Finally, you'll use NLP to integrate a voice UX through Dialogflow on your web pages. By the end of this book, you'll have learned how to deploy intelligent web apps and websites with the help of effective tools and practices.

Using the API via cURL and creating a web client using Flask

With our server running, we can send POST requests to it with the image content and expect a predicted digit in the output. Two ways to test any API without any third-party tools are as follows:

  • Use cURL.
  • Develop a client to call the API.

We will be covering both of these methods.

Using the API via cURL

Before we develop a client to send POST requests to the API server, let's test the API via cURL, which is a command-line tool used to simulate GET and POST requests to URLs.

Use the following command in Terminal or Command Prompt to make a curl request to your prediction API:

curl -X POST -F img=@"path_to_file" http://localhost/predict/
