When executing "Performing train/eval split...", an error occurred.

[LUORANCHENG]

system:ubuntu22.04
colmap camera model:PINHOLE or SIMPLE_PINHOLE

When I run python train_full_pipeline.py -s /home/ihavc/MyProject/SuGaR/data/nerf_synthetic/lego -r dn_consistency --high_poly True --export_obj True, the first stage runs normally and I get the vanilla Gaussian Splatting model, but I encounter an error during the second stage at "Performing train/eval split...":

I think this error is caused by an incorrect format in the camera parameter file. I used the PINHOLE or SIMPLE_PINHOLE camera model in COLMAP to generate the camera parameter file.
