Completely black rendering images

[ScienceLi1125]

I reproduced this project a year ago, and it ran successfully and achieved great results.

However, when I reproduced this project again, It didn't work as I expected. I found that the loss function of the training process did not decrease, and the PSNR was very low (about 7 to 9). Then, when I rendered the image after training, the rendered images was completely black (RGB 000).

Why did this happen? I tried the solution in Loss not significantly decreasing #1050: git submodule update --init --recursive --remote, but it didn't work.
