I installed gsplat: 0.1.10, igs2gs: 0.1.0.
Thank you for helping with this issue.

Hello, which version of Nerfstudio are you using? I recommend using the latest one from the nerfstudio main branch since there were some recent changes to splatfacto. Let me know if the error still appears.

Hello, Thank you for your reply.
Nerfstudio version is 1.0.3.
I updated the version.
I keep experiencing the same error.

I'm having trouble reproducing that error. On my system, it is working with the latest main branch of instruct-gs2gs and nerfstudio. Did you install nerfstudio from pip or from source from the main git branch?
