when i run the python visualize.py,it arise this error:
Traceback (most recent call last):
File "/root/safer-splat-master/visualize.py", line 85, in
server.scene.add_gaussian_splats(
AttributeError: 'SceneApi' object has no attribute 'add_gaussian_splats'. Did you mean: '_add_gaussian_splats'?

if i use _add_gaussian_splats,it arise :

This error is simply an import error. The viser package that comes default with nerfstudio lacks some features; our codebase requires the most up-to-date viser version. Simply go to the viser repo (https://github.com/nerfstudio-project/viser) and do a pip upgrade. This should fix your issue.

After visualizing, I got this obj, but I'm not quite sure what it's trying to convey.
