When I used S3DIS dataset, there was a miatake about file operation.As follows:

How to change this code" scene_files = np.concatenate([scene_paths[i] for i in split_inds], axis=0)"

Hi, if you are using Windows, replace the backslashes with forward slashes before splitting. I replaced:

scene_files = np.concatenate([scene_paths[i] for i in split_inds], axis=0)

By

        # Handle paths in a platform-independent way
        scene_names = []
        for f in scene_files:
            parts = f.replace('\\', '/').split('/')
            scene_names.append(f"{parts[-2]}_{parts[-1]}")

It's working for me now.
