single class training issus

[riyaj8888]

when i am training yolov2 for single class i am getting following error.
" net_utils.load_net(args.model, net)
File "/home/ubuntu/projects/lesiondetectlong/utils/network.py", line 63, in load_net
v.copy_(param)
RuntimeError: The expanded size of the tensor (30) must match the existing size (60) at non-singleton dimension 0
"
when i printed out the output channels of conv5 layers it has to show "out_channels = num_anchors * (num_classes + 5) "
for single class it must be 30 .
but i am getting 60 output channels
