Chapter 5: Pretraining on Unlabeled Data

ch05.ipynb contains all the code as it appears in the chapter
previous_chapters.py is a Python module that contains the MultiHeadAttention module and GPTModel class from the previous chapters, which we import in ch05.ipynb to pretrain the GPT model
gpt_train.py is a standalone Python script file with the code that we implemented in ch05.ipynb to train the GPT model (you can think of it as a code file summarizing this chapter)
gpt_generate.py is a standalone Python script file with the code that we implemented in ch05.ipynb to load and use the pretrained model weights from OpenAI
gpt_download.py contains the utility functions for downloading the pretrained GPT model weights
exercise-solutions.ipynb contains the exercise solutions for this chapter
