I encountered the same problem with you. Could I ask that have you solved it?

[kmonachopoulos]

No I haven't try anything. Maybe consider switching to another repo could help ...

I am facing the same problem

I found there is no Forward_gpu function in detection_loss_layer,so I think it can not use GPU to train.
