Viewer crash

[jb-ye]

Describe the bug

I am training splatfacto, during which I open the viewer. In the viewer, I tried to reset the resolution from default 512 to 1024, I got the above crash and the viewer basically freeze. It happens during early stage of training when coarse-to-fine training is active.

Exception in thread Thread-11:
Traceback (most recent call last):
  File "/opt/conda/envs/nerfstudio/lib/python3.10/threading.py", line 1009, in _bootstrap_inner

@brentyi This seems related to the depth rendering scaling factor

[brentyi]

Yeah, the error implies we're getting 0 from current_depth_pixels = outputs["depth"].shape[0] * outputs["depth"].shape[1]. Probably there's an edge case in _calculate_image_res, or how client camera aspect ratios are read/used?

It also happen to me with same exact error message...
