Does Nerf-W evaluate PSNR as well?

[CultureAddiction]

I tried some of phototourism example(https://github.com/kwea123/nerf_pl/releases/tag/nerfw_branden), but none of phototourism examples did not evaluate mean psnr value. None of mine does nor none of examples in the link does.

On your code(eval.py), it seems variable 'psnrs' does not have any element, as "print(f'Mean PSNR : {mean_psnr:.2f}')" (line 224) does not shows up.
I guess it occurs because dictionary 'sample' does not have 'rgb' keyword (line 212, "if 'rgbs' in sample:"), which means dataset[i] does not have 'rgb' keyword as well (line 190, "sample = dataset[i]").
But on my root directory, I do have rgb images.

Why is this happening?
Is the PSNR value could only be executed on the lego examples?

+) Reading datasets/phototourism.py, It seems datasets[i] does not contain rgbs keyword because of split 'test' goes to the else clause, which do not assign rgbs keyword (while split=val, test_train assign rgbs at line 221). Is this some miswritten code refering to the 'test_train' instead? Or does else clause at phototourism.py intends for the eval.py?
