Hello, thank you for this detailed issue!
in the next days I will split the test set in multiple files to make it easier to download. Regarding the few images that were lost, is it only those 5? If only a few images were lost, I can send them to you privately.
the training time that you get is way slower than it should be. To check if the data loading is the bottleneck you can comment all steps in the training loop except for the data loading. In this code, comment everything after this line. Then launch the script again. If it is much faster, then data loading was not the issue. If it is still slow (i.e. ~2 hours per epoch), then data loading is the issue, and it might be due to non-performant HDD.
the benchmark is a different paper from the one in this repo. In the benchmark we mostly focus on previous literature, which is based on the seminal NetVLAD paper. They do early stopping, so we do early stopping in the benchmark. On the other hand, CosPlace is a newer paper that presents a new method. We like to keep things simple so we don't use early stopping, although using it might improve the results a bit.
I hope this helps! Let me know if everything is clear
Thank you! Your answers and suggestions are very helpful.

Hello!
I downloaded SF-XL-small and SF-XL-processed. However, I can't download the test set(116 GB) of the SF-XL-processed completely. The first few times the download was interrupted, the last download was successful, but a few images were lost. (This problem may only be encountered by Chinese researchers. Our network has some limitations.) So I have a suggestion, you can split the test set into multiple unpacks. This makes it easier for researchers to follow your work and increase your citations.
I used a 3090 Ti to train on the SF-XL-processed, which was very slow and not consistent with what you said in #4 . Can you give me some suggestions? (I put data on a mechanical hard drive, could this be the reason?)
I noticed that you use early stopping strategy in VG Benchmark, but you fix 50 epochs in CosPlace. These settings confuse me.
Looking forward to your reply! Thank you!
