Command line arguments

[jacobjinkelly]

Command line arguments should be configured so that results can be reproduced, and one can run new experiments, without having to modify any of the actual codebase. I'm having some issues in doing this with the current project structure (i.e. one has to import a level up) and also with the ugliness of passing parameters from command line args to functions (I haven't been able to find a nice way to do this, i.e. something like f(*args, **kwargs)).

Some thoughts -

You could convert command line args into a dictionary and then passes it in as **kwargs (e.g., https://stackoverflow.com/questions/12807539/how-do-you-convert-command-line-args-in-python-to-a-dictionary).

You could also directly pass in args into run() in main.py. The run() functions can then take whatever parameters they need from the args. For example, instead of doing

def run():
    name = "train"
    is_ptr = True
    hidden_dim = embedding_dim = 256
    [the rest of your code]

you can just do

def run(args):
    name = args.name
    is_ptr = args.ptr
    hidden_dim = embedding_dim = args.hidden_dim
    [the rest of your code]
