Value error

when I train the model , I have some problems Validation sanity check: 0it [00:00, ?it/s]/root/miniconda3/lib/python3.8/site-packages/pytorch_lightning/trainer/data_loading.py:110: UserWarning: The dataloader, val_dataloader 0, does not have many workers which may be a bottleneck.

If you want to disable validation setlimit_val_batches` to 0.0 instead.

what can I do to solve it

https://github.com/hjxwhy/mipnerf_pl/blob/6c074522cd6246281391fdfdbe9e155a1f846ac2/configs/lego.yaml#L16 change this value less than 1303(which is all your training samples) the error message has pointed out it.
