I also meet this problem. I find another person post this issue but is not replied. I'm looking forward to a solution. Thank you!

Hi, so our code is on a branch mentioned in the README. It's using an older version of Nerfstudio, which probably contributes to this error. You might wish to reference this branch and incorporate parts you want into your own codebase, given that Nerfstudio keeps improving. https://github.com/nerfstudio-project/nerfstudio/tree/nerfbusters-changes
