To get the most out of this book
Most of the programs in the book are Jupyter notebooks. All you will need is a free Google Gmail account, and you will be able to run the notebooks on Google Colaboratory’s free VM.
Take the time to read Chapter 2, Getting Started with the Architecture of the Transformer Model. Chapter 2 contains the description of the Original Transformer. If you find it difficult, then pick up the general intuitive ideas from the chapter. You can then go back to that chapter when you feel more comfortable with transformers after a few chapters.
After reading each chapter, consider how you could implement transformers for your customers or use them to move up in your career with novel ideas.

Conventions used
There are several text conventions used throughout this book.
CodeInText: Indicates sentences and words run through the models in the book, code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example, “However, if you wish to explore the code, you will find it in the Google Colaboratory positional_encoding.ipynb notebook and the text.txt file in this chapter’s GitHub repository.”
A block of code is set as follows:
import numpy as np
from scipy.special import softmax
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
The black cat sat on the couch and the brown dog slept on the rug.
Any command-line input or output is written as follows:
vector similarity
[[0.9627094]] final positional encoding similarity
Bold: Indicates a new term, an important word, or words that you see on the screen.
For instance, words in menus or dialog boxes also appear in the text like this. For example:
“In our case, we are looking for t5-large, a t5-large model we can smoothly run in
Google Colaboratory.”
Warnings or important notes appear like this.
Tips and tricks appear like this.
