I had train yolov3 use pytorch 0.4,but yesterday I  update my pytorch version to 1.0. So a error come out, this is error message.
cannot perform reduction function max on tensor with no elements because the operation does not have an identity.
I think this code is the bad code for version 1.0.
loss_cls = (1 / nB) * self.ce_loss(pred_cls[mask], torch.argmax(tcls[mask], 1)).
Is there any one help me
