Applying CamP to mipnerf360 datasets degrades PNSR and SSIM values

[ppponpon]

Hi, first of all thanks for this great paper and code. I finally managed to get your code to work!!
First, I tried to a task of replicating Table 1 in your paper for Single-Scale mipnerf360 dataset(7samples (bicycle,bonsai,counter,garden,kitchen,room,stump)), comparing with to without CamP.
Unfortunately, the average value of psnr:30.68,ssim:0.89(without CamP) degraded to psnr:27.43,ssim:0.82(with Camp)!
I used zipnerf/360_train.sh, zipnerf/360_eval.sh and zipnerf/360_render.sh, only rewriting DATA_DIR and CHECKPOINT_DIR, for w/o CamP.
And I used camp/360_train.sh, zipnerf/360_eval.sh and zipnerf/360_render.sh, rewriting DATA_DIR and CHECKPOINT_DIR and add option "-gin_configs=configs/camp/camera_optim.gin" for zipnerf/360_eval.sh and zipnerf/360_render.sh , for with CamP.

Unit test is all OK(with JAX), and Single-Scale mip-NeRF 360 Dataset Results of zipnerf(psnr,ssim) are roughly the same or better.
What do you think could be the reason it isn't working?

i.e. At garden sample,psnr:28.28,ssim:0.8664(without CamP) ,psnr:25.92,ssim:0.7548(with CamP).
Does CamP make the alignment worse?
What values ​​did everyone get?
Am I misunderstanding the results?
