If you want to use bools without store-true or store-false, you need to define an str2bool function:
[https://stackoverflow.com/questions/15008758/parsing-boolean-values-with-argparse Stack Overflow Answer]
<syntaxhighlight lang="python">
def str2bool(val):
  """Converts the string value to a bool.
  Args:
    val: string representing true or false
  Returns: bool
  """
  if isinstance(val, bool):
    return val
  if val.lower() in ('yes', 'true', 't', 'y', '1'):
    return True
  elif val.lower() in ('no', 'false', 'f', 'n', '0'):
    return False
  else:
    raise argparse.ArgumentTypeError('Boolean value expected.')
#...
parser.add_argument("--augment",
                    type=str2bool,
                    help="Augment",
                    default=False)
</syntaxhighlight>
