Hello, thank you for your great work. I'd like to train your code by candlefiat, I faced below errors. do you know how to use training dataset?

`Output folder: /cig/common06nb/deserizk/HDRSplat/output/candlefiat Optimizing /cig/common06nb/deserizk/HDRSplat/output/candlefiat /cig/common06nb/deserizk/archive/rawnerf/scenes/candlefiat/sparse [16/10 15:35:51] demosaic [16/10 15:35:51]

3DGS implementation only supports simple pinhole camera model for now, to convert the dataset to simple pinhole camera model, install colmap CLI and follow these steps:

$ DATASET_PATH=/path/to/dataset

$ colmap feature_extractor \ --database_path $DATASET_PATH/database.db \ --image_path $DATASET_PATH/images

$ colmap exhaustive_matcher \ --database_path $DATASET_PATH/database.db

$ mkdir $DATASET_PATH/sparse

$ colmap mapper \ --database_path $DATASET_PATH/database.db \ --image_path $DATASET_PATH/images \ --output_path $DATASET_PATH/sparse

$ mkdir $DATASET_PATH/dense

$ colmap image_undistorter \ --image_path $DATASET_PATH/images \ --input_path $DATASET_PATH/sparse/0 \ --output_path $DATASET_PATH/dense \ --output_type COLMAP \ --max_image_size 2000
