看着挺好玩

 再插入一个代码行

 1 import argparse
 2 
 3     # 解析命令行参数
 4     parser = argparse.ArgumentParser(
 5         description='Train Mask R-CNN to detect balloons.')
 6     parser.add_argument("command",
 7                         metavar="<command>",
 8                         help="'train' or 'splash'")
 9     parser.add_argument('--dataset', required=False,
10                         metavar="/path/to/balloon/dataset/",
11                         help='Directory of the Balloon dataset')
12     parser.add_argument('--weights', required=True,
13                         metavar="/path/to/weights.h5",
14                         help="Path to weights .h5 file or 'coco'")
15     parser.add_argument('--logs', required=False,
16                         default=DEFAULT_LOGS_DIR,
17                         metavar="/path/to/logs/",
18                         help='Logs and checkpoints directory (default=logs/)')
19     parser.add_argument('--image', required=False,
20                         metavar="path or URL to image",
21                         help='Image to apply the color splash effect on')
22     parser.add_argument('--video', required=False,
23                         metavar="path or URL to video",
24                         help='Video to apply the color splash effect on')
25     args = parser.parse_args()
26 
27     # 验证参数，使用assert语法。
28     if args.command == "train":
29         assert args.dataset, "Argument --dataset is required for training"
30     elif args.command == "splash":
31         assert args.image or args.video, "Provide --image or --video to apply color splash"
