请问我的代码哪里出问题了呢？

Question

在运行代码的过程中遇到报错：
AttributeError: 'NoneType' object has no attribute 'seed'

报错部分代码：

def options():
    parser = argparse.ArgumentParser(description='tpccNet: A Fully-Convolutional Network For Inlier Estimation (Training)')
    parser.add_argument('--exp_name', type=str, default='exp_tpccnet', metavar='N',
                        help='Name of the experiment')
    
    
    # settings for on training
 
    parser.add_argument('--seed', type=int, default=1234)
    
    args = parser.parse_args()
    return args

def main():
    args = options()
    torch.backends.cudnn.deterministic = True
    torch.manual_seed(args.seed)                                  #此处报错
    torch.cuda.manual_seed_all(args.seed)
    np.random.seed(args.seed)
 
    boardio = SummaryWriter(log_dir='checkpoints/' + args.exp_name)
    _init_(args)
 
    textio = IOStream('checkpoints/' + args.exp_name + '/run.log')
    textio.cprint(str(args))

请问是什么原因呢？有没有什么解决方法？

谢谢！

加一个返回值应该可以

 
def options():
    parser = argparse.ArgumentParser(description='tpccNet: A Fully-Convolutional Network For Inlier Estimation (Training)')
    parser.add_argument('--exp_name', type=str, default='exp_tpccnet', metavar='N',
                        help='Name of the experiment')
    
    
    # settings for on training
 
    parser.add_argument('--seed', type=int, default=1234)
    return parser
