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.

Step 4: Checking the version of TensorFlow

The GPT-2 345M transformer model provided by OpenAI uses TensorFlow 1.x. This will lead to several warnings when running the program. However, we will ignore them and run at full speed on the thin ice of training GPT models ourselves with our modest machines.

In the 2020s, GPT models have reached 175 billion parameters, making it impossible for us to train them ourselves efficiently without having access to a supercomputer. The number of parameters will only continue to increase.

The corporate giants’ research labs, such as Facebook AI and OpenAI, and Google Research/Brain, are speeding toward super-transformers and are leaving what they can for us to learn and understand. But, unfortunately, they do not have time to go back and update all the models they share. However, we still have this notebook!

TensorFlow 2.x is the latest TensorFlow version. However, older programs can still be helpful. This is one reason why Google...
