title: How do I train gpt 2 from scratch?
body: <p>I want to train gpt 2 from scratch but there is only fine-tuning approach based on pretrained models in articles I found.
  I've used this <a href="https://github.com/nshepperd/gpt-2" rel="noreferrer">https://github.com/nshepperd/gpt-2</a> for train with existing model. Should I edit these Python scripts to train from scratch?</p>
