Right, I do this with argparse for creating simple CLIs for a module generally intended to be imported and used in another program. argparse has nothing to do with the actual module functions and won't be needed if the module if going to be used in a web app or some other context.
This make even more sense for a non-standard library like fire because you won't even need this dependency if you're going to import the module and write your own interface instead.
The import in main doesn't seem particularly useful in context on a quick read, but considering the line
> utils.py contains the code to download and load the GPT-2 model weights, tokenizer, and hyper-parameters.
it seems possible some downloads are happening on import so does make sense to defer until actually needed, as suggested in sibling comments.
