    parser.add_argument('data', type=str, help="path to data")
    parser.add_argument('output', type=str, help="model save path")
    parser.add_argument('batch_size', type=int, help="batch size")
    parser.add_argument('epochs', type=int, help="no.s of epochs")
    args = parser.parse_args()
print(args.data + args.output + args.batch_size + args.epochs)

train.py /path/to/data/ /path/to/output_files/ 128 100
