Nerfstudio not converging after 17000+ steps - scene still blurry

Open desifisker opened this issue 1 year ago • 5 comments

I've just downloaded nerfstudio and have been trying to get the example of the poster dataset to work. as far as I know, I followed the steps in the documentation to get to this result, but the viewer only shows a blurry scene despite it training for a while. Am I missing something? Screenshot from 2024-08-11 22-23-49

Have you tried rendering a video and downloading it? (second tab) Can you try that please if you haven't already?

Depending on your GPU dropping the "Train Util" slider can also help, or pausing training. It looks like the viewer code is only streaming renders of size 26x30 which feels quite small...!

@desifisker you're setting max_res = 256 so ofc it's blurry. can you try increasing it?

@hoanhle I have tried. not sure if im doing it right, but dragging the slider while its training makes absolutely no difference. I know the viewer is supposed to be dynamic, but I have been training the instant-ngp model on poster for an hour now and the scene doesn't move or change, even when I try to navigate with wasd or arrows.

@brentyi thanks for the feedback, i tried pausing the training and adjusting the util slider but nothing in the viewer changed at all.
