Regarding arguments in train.py

[benihime91]

Hi. First of all thank you for this wonderful library @rwightman .

Had a few doubts what do these arguments mean in the train.py script

parser.add_argument('--drop', type=float, default=0.0, metavar='PCT',
                    help='Dropout rate (default: 0.)')
parser.add_argument('--drop-connect', type=float, default=None, metavar='PCT',
                    help='Drop connect rate, DEPRECATED, use drop-path (default: None)')
parser.add_argument('--drop-path', type=float, default=None, metavar='PCT',
                    help='Drop path rate (default: None)')
parser.add_argument('--drop-block', type=float, default=None, metavar='PCT',
                    help='Drop block rate (default: None)')

If I am not wrong, drop means to dropout in the between the classifier and the pool_layer. What do the other arguments specify ?
