AttributeError: Can't pickle local object 'trainer_synapse.<locals>.worker_init_fn'

错误原因：Can't pickle local object 'trainer_synapse.<locals>.worker_init_fn'

解决办法：把trainer.py里面trainloader当中的num_workers改成0

改后：

2.

报错信息：FileNotFoundError: [Errno 2] No such file or directory: './data/Synapse/train_npz\\train_npz\\case0005_slice002.npz'

解决办法：把train.py文件当中的

parser.add_argument('--root_path', type=str,
                    default='./data/Synapse/train_npz', help='root dir for data')

改成

parser.add_argument('--root_path', type=str,
                    default='./data/Synapse', help='root dir for data')
