复现Swin-UNet出现报错train.py: error: the following arguments are required: --cfg

报错内容：

usage: train.py [-h] [--root_path ROOT_PATH] [--dataset DATASET]

                [--output_dir OUTPUT_DIR] [--max_iterations MAX_ITERATIONS]

train.py: error: the following arguments are required: --cfg

解决方法：

parser.add_argument('--cfg', type=str,default='./configs/swin_tiny_patch4_window7_224_lite.yaml',metavar="FILE", help='path to config file', )

##config这里加了default，把required=ture删掉了

顺利解决
