n_scales parameter

[CharlesAntoineParent]

Hello ! I was wondering why there was an option to configure the number of scale produce by the feature extractor if nf blocks are always supposed to get 3 scales ? Thank you

Hi, unfortunately, there is currently no option to configure the number of scales. n_scales is used for many parts of the code for readability, but not for the NF architecture itself.

Thank you for the quick answers. I was wondering if you tried getting multi scale representation by using a backbone that produces different scales only with one propagation (like Darknet + Path aggregation network in yolo) instead of getting representation by doing multiple propagation in the backbone ?

I tried this, but got a slightly worse performance for MVTec. It might be beneficial for other datasets.
