How to use this to work on real dataset?

If you use COLMAP to solve for the camera poses, you can use the LLFF dataloader after reading the COLMAP output.
You can find more details about this in the original author's TF implementation https://github.com/bmild/nerf

If you have your own poses, you can write them into .json files and use the blender dataloader.
