Pytorch错误之SystemExit: 2解决方法

1.错误行

opt = parser.parse_args()

usage: ipykernel_launcher.py [-h] [--num_classes NUM_CLASSES]
                             [--epochs EPOCHS] [--batch-size BATCH_SIZE]
                             [--lr LR] [--lrf LRF] [--data-path DATA_PATH]
                             [--weights WEIGHTS]

SystemExit: 2

2.正确行

opt = parser.parse_args(args=[])

具体我也不清楚为什么，加上错误就解决了！
