Training a GPT-2 language model

In this section, we will train a GPT-2 model on a custom dataset that we will encode. We will then interact with our customized model. We will be using the same kant.txt dataset as in Chapter 4, Pretraining a RoBERTa Model from Scratch.

We will open the notebook and run it cell by cell.

Step 1: Prerequisites

The files referred to in this section are available in the AppendixIV directory of this book’s GitHub repository:

Activate the GPU in the Google Colab’s notebook runtime menu if you are running it on Google Colab, as explained in Step 1: Activating the GPU in Appendix III, Generic Text Completion with GPT-2.
Upload the following Python files to Google Colaboratory with the built-in file manager: train.py, load_dataset.py, encode.py, accumulate.py, memory_saving_gradients.py.
These files originally come from N Shepperd’s GitHub repository: https://github.com/nshepperd/gpt-2. However, you...
