Hello,

I have noticed the prediction images contain darkened first line (and also the left and right borders). It might be caused by zero-padding in the Conv2D layer, but I have not investigated the issue in-depth.

Example input image: gcanyon_c_yumapoint_3k exr

Original pixel values (a screenshot of the tev image viewer):

Please let me know in case you need more information.

Hi, sorry for the late response. I replicated the issue and found the culprit. It was the replacespecials function which was attempting to remove infs and NaNs from the input. It wasn't properly working so I just removed it since it doesn't add much value, and it fixes the problem.
