Hi
I am trying to train the model on my custom data, run python3 apps/calibration/read_colmap.py ../../data/xx/sparse/0 --min_views 2 firstly, then got some errors when training, command is python3 apps/train.py --cfg config/example/test/train.yml split train

Hi, it seems there might be some issues with your camera parameters and point cloud.

To ensure that the point cloud in the dataset is correctly projected, try the following command:

python3 apps/test_pointcloud.py --cfg config/example/test/dataset.yml split dataset radius 0.01

The output will be directed to the debug/ directory.
