Overview of this book

Transformers are...well...transforming the world of AI. There are many platforms and models out there, but which ones best suit your needs? Transformers for Natural Language Processing, 2nd Edition, guides you through the world of transformers, highlighting the strengths of different models and platforms, while teaching you the problem-solving skills you need to tackle model weaknesses. You'll use Hugging Face to pretrain a RoBERTa model from scratch, from building the dataset to defining the data collator to training the model. If you're looking to fine-tune a pretrained model, including GPT-3, then Transformers for Natural Language Processing, 2nd Edition, shows you how with step-by-step guides. The book investigates machine translations, speech-to-text, text-to-speech, question-answering, and many more NLP tasks. It provides techniques to solve hard language problems and may even help with fake news anxiety (read chapter 13 for more details). You'll see how cutting-edge platforms, such as OpenAI, have taken transformers beyond language into computer vision tasks and code creation using DALL-E 2, ChatGPT, and GPT-4. By the end of this book, you'll know how transformers work and how to implement them and resolve issues like an AI detective.

Appendix I — Terminology of Transformer Models

Steps 6-7: Intermediate instructions

In this section, we will go through Steps 6, 7, and 7a, which are intermediate steps leading to Step 8, in which we will define and activate the model.

We want to print UTF-encoded text to the console when we are interacting with the model:

#@title Step 6: Printing UTF encoded text to the console
!export PYTHONIOENCODING=UTF-8

We want to make sure we are in the src directory:

#@title Step 7: Project Source Code
import os # import after runtime is restarted
os.chdir("/content/gpt-2/src")

We are ready to interact with the GPT-2 model. We could run it directly with a command, as we will do in the Training a GPT-2 language model section of Appendix IV, Custom Text Completion with GPT-2. However, in this section, we will go through the main aspects of the code.

interactive_conditional_samples.py first imports the necessary modules required to interact with the model:
