Implementation bug about unlabeled_matching_layer?

[serend1p1ty]

https://github.com/Cysu/caffe/blob/aed38841ae4282d90575186b87c3287620913722/src/caffe/layers/unlabeled_matching_layer.cu#L48
caffe_gpu_memcpy is based on bytes, so the code should be:

caffe_gpu_memcpy(K * sizeof(int), bottom_data + i * K, weight + queue_tail_ * K);

The shape of queue that saves the features of unlabeled persons is (5000, 256)
But I find only the first 64 columns of the variable queue have values.
Because of 64 = 256 / sizeof(int).
