When running Semantic-NeRF-W with sitcoms3D in nerfstudio, it failed and displayed the error message "images4 not found."

[fxyfengxiaoyi]

Error message: FileNotFoundError: [Errno 2] No such file or directory: 'nerfstudio/data/sparse_reconstruction_and_nerf_data/ELR-apartment/images_4/ELR_S09E04_00011276.jpg'

1.Manually download the sparse_reconstruction_and_nerf_data from sitcoms3D.
2.Run the command:ns-train semantic-nerfw --data data/sparse_reconstruction_and_nerf_data/ELR-apartment/

I have indeed downloaded the sparse_reconstruction_and_nerf_data/ELR-apartment folder, but there's no images_4 directory. Could you please tell me what went wrong?

Thank you very, very much for your response!
