How to evaluate the method on my own dataset

[Yingsheng123]

I notice that there is checkpoint named ckpt_29999_rank0.pt, how this is generated？

I generated that checkpoint using gsplat (https://github.com/nerfstudio-project/gsplat). In their repo, in the examples folder, you can find a script simple_trainer.py. You can use that script to train the dataset. Make sure you are not normalizing the world space. You can see various command line parameters by python simple_trainer.py --help. Alternatively, you can create the checkpoint with https://github.com/graphdeco-inria/gaussian-splatting
