Hello, thank you very much for sharing your code. I am currently trying to reproduce your code on the YFCC dataset. However, when I use your dump/download_data.sh script, I receive a 503 error. Upon inspecting the internal script code, I noticed that you are downloading the dataset from https://research.altizure.com/data/oanet_data/raw_data.tar, but I still cannot download it. Is it possible that there is an issue with the website? Could you please provide more details?
