Steps with my own indoor data

Hello, thanks for really great work. I would like to use your algohorithm to match/find simillar scenes in the indoor photos. I think hloc is the tool I need but I'm having problem with correctly run yours demo code in the colab notebook.

This is my doubts and problems:

I try run 'pipeline_InLoc.ipynb' file, with my own data (own indoor image samples) is enought that I have only image ? Meyby other data is necessary (like 3D scan) ?
I got in the line: match_path = match_features.main(matcher_conf, loc_pairs, feature_conf['output'], outputs) error:

                "215 loader = torch.utils.data.DataLoader(
                    216     dataset, num_workers=5, batch_size=1, shuffle=False, pin_memory=True)
                    217 writer_queue = WorkQueue(partial(writer_fn, match_path=match_path), 5)
                --> 219 for idx, data in enumerate(tqdm(loader, smoothing=.1)):
                    220     data = {k: v if k.startswith('image')
                    221             else v.to(device, non_blocking=True) for k, v in data.items()}
                    222     pred = model(data)
                ...
                  File "h5py[/_objects.pyx](https://file+.vscode-resource.vscode-cdn.net/_objects.pyx)", line 54, in h5py._objects.with_phil.wrapper
                  File "h5py[/_objects.pyx](https://file+.vscode-resource.vscode-cdn.net/_objects.pyx)", line 55, in h5py._objects.with_phil.wrapper
                  File "h5py[/h5o.pyx](https://file+.vscode-resource.vscode-cdn.net/h5o.pyx)", line 190, in h5py.h5o.open
                KeyError: 'Unable to open object (component not found)' "

To resolve it I think I have to use script 'hloc/pairs_from_retrieval.py' berofe, I have right ? If yes then why,

If I can be honest I don't understood 'pairs' concept in yours code. For example I have pair files path in this txt file : 'Hierarchical-Localization/pairs/inloc/pairs-query-netvlad40-temporal.txt', what is different between this images and images from main dataset ? Why I must have this pair list. I think this question is related to the previous one aslo.

I know that's a lot of questions, but the answers to them would be helpful for me. Thanks in advance for your help and best regards.
