PSNR:Nan

[qiufengyuzhi]

Excuse me, I referred to the above conversation to modify my code, but still haven't solved the problem of the PSNR value being nan. I think the model still hasn't read the dataset. I would be very grateful if there have any suggestions about my problem.

python main.py --n_GPUs 1 --rgb_range 1 --chunk_size 144 --n_hashes 4 --save_models --lr 1e-4 --decay 200-400-600-800 --epochs 1000 --chop --save_results --n_resblocks 32 --n_feats 256 --res_scale 0.1 --batch_size 16 --model NLSN --scale 2 --patch_size 96 --save NLSN_x2 --data_train DIV2K
