title: Problems about torch.nn.DataParallel
body: <p>I am new in deep learning area. Now I am reproducing a paper’s codes. since they use several GPUs, there is a command <code>torch.nn.DataParallel(model, device_ids= args.gpus).cuda()</code> in codes. But I only have one GPU, what
  should I change this code to match up my GPU?</p>
  
  <p>Thank you!</p>
