It's ok but for some scripts it ends up being half of the code and you end up with a script that's dealing with an opaque args object.

Here's a decent example of this https://github.com/pytorch/examples/blob/master/imagenet/mai...

Could you solve ghat with click much easier? This seems mostly related to various flags set up, which would need to exist in the code anyway.

I'm saying that this should really be a function like

    def train(
      data: File,
      arch='resnet18',
      workers=4,
      epochs=90,
      start_epoch=0,
      batch_size=256,
      learning_rate=0.9,
      momentum=1e-4,
  ):
    ...

that could be exposed as a cli if __name__ is main but otherwise can be imported in a notebook or another script.
