Errors when running the demo

[markinruc]

Thanks for your great work!
I met the error when running the demo. I guess it may be a problem with the HLOC, but I don't know how to solve it.

The error message is shown in the image below.

I would greatly appreciate it if you could help me solve it！
Thank you!

Hi,

I think it is because Hloc cannot find any pairs in your specific folder, where you can say it "Found 0 pairs". Although it seems you are running on samples/apple, can you double check what's the value of folder_path in your work? Probably there is not any image in your folder_path.
