Hi,
thank you for your code.
I have a question about the code 'f=f.detach()' in ft_netAB of reIDmodel.py.
Since f set to to be detached, then loss(4) in your paper will have two appearance codes which are both inable to backward，thus the loss with be useless. Moreover, since f is used to reconstruct images, then losses for image reconstruction will also have no effect for Ea's updating.
I'm so confused, thank you for your kind explanation!
