Reproducing performance on DTU

[hongsukchoi]

Hi, I read the main manuscript and supplementary material, but can't find the training detail for DTU dataset.
How many epochs did you train on DTU dataset?
I trained quite a lot, but cannot reproduce the table 3 here.

Hello @hongsukchoi, I think I managed to reproduce it, or at least got close to it. I trained in the default setting (only with the batch size reduced by 2 from the default 4) and took about 300~ epochs to converge (about 4-5 days with an RTX 2080Ti). My model got a PSNR of 18.499 and an SSIM of 0.679 on the 3 views DTU evaluation.

hello, I am trying to reproduce it on the DTU, too. But every epoch takes about 2.5 hours with 3 RTX 2080Ti, for it repeats DTU 32 times in one epoch. I was wondering how could it run 300 epochs during 4-5 days with an RTX 2080Ti.

Hello @danperazzo , thank you for your information! Could I ask why do you reduce batch size from 4 to 2?

Hello all, this was resolved in the following thread #62

pip install --force-reinstall -v "pyhocon==0.3.55"

Hello! When I try to run eval.py, it cannot find con/resnet_fine_mv.conf. How did you solve this problem?
