sdf mode PSNR problem

[trebladev]

Hi,
I just use the scripts/runall_syn_sdf.sh to run sdf mode.
But I found that the PSNR of sdf mode is just 18 in chair scene, I get 34 without sdf mode.
Is that normal?
Thanks.

And when I train the ship, it will error below when epoch 40-45

貌似sdf模式不仅降低了psnr的值，而且训练速度也很慢。

I also encountered the same problem NaN or Inf found in input tensor for certain examples. @trebladev Have you found the fix?

[juuso-oskari]

Same error here, at least with the synthetic scenes

same problem. Wondering reason. also be seen in #96

here is some result in lego
