About hybrid memory re-id loss implementation
Hi, I have question about the implementation in hm.py loss.
Why did you use masked_softmax in the above code?
and also what is the meaning of below code?
nums = torch.zeros(labels.max()+1, 1).float().cuda()
nums.index_add_(0, labels, torch.ones(self.num_samples,1).float().cuda())
mask = (nums>0).float()
sim /= (mask*nums+(1-mask)).clone().expand_as(sim)
I think this code is same as SPCL re-ID code, but there is not much explantation.
Is using masked re-ID loss neccessary?
Runtimeerror during training
About len_iter
Lines 84 to 91 in a77577e
In that part of the code, CUHK-SYSU specifies len_itr as 2240, but the train_log you uploaded shows 1420. Why is there such a difference?
About 'undetected person'
About implementation details
Hi. Thank you for your great work.
I was wondering why is the LUT_SIZE=6015
when the target domain is set to CUHK-SYSU?
Also the CUHK-SYSU(11,206) has more scene images than PRW(5,704).
If the batch size is set to 4 (2 for CUHK and 2 for PRW),
in each epoch are there some images in CUHK-SYSU that are not fed into the model for training?
