How to reproduce using the latest master (018a1e1796d7ea3e96032d9667042316c8fa7864) on macOS M1:

$ python gpt2.py "Alan Turing theorized that computers would one day become" -n 8
generating: 100%|█████████████████████████████████| 8/8 [00:03<00:00,  2.44it/s]
 the most powerful machines on the planet.

Then apply the following patch:
