ProPainter 请问运行train.py时卡住了怎么处理？

我在运行python train.py -c configs/train_propainter.json时，显示下面这种情况

(propainter) ➜ ProPainter git:(main) ✗ python train.py -c configs/train_propainter.json world_size: 4 using GPU 0-0 for training [**] create folder experiments_model/propainter_train_propainter using GPU 1-1 for training using GPU 2-2 for training using GPU 3-3 for training Pretrained flow completion model has loaded...

另外运行python train.py -c configs/train_flowcomp.json时也一直停在0%这儿，请问这个怎么处理？
