Can't find dataloader , no outputs

[BaiLuQiShuang]

When i ran predict.py , here comes the issues:
[2024-07-03 10:59:17,943][saicinpainting.training.trainers.base][INFO] - BaseInpaintingTrainingModule init done
0it [00:00, ?it/s]
[2024-07-03 10:59:18,323][saicinpainting.training.data.datasets][INFO] - Make val dataloader default from E:\PythonProjectFiles\lama\images/

I also changed the model.path, indir, outdir, make sure they are not empty.
So what's val dataloader?
Thank you very much for answering my questions! 👍 :)
