Training issue

[leonardoaraujosantos]

Hi, I've cloned the code today and try the training and got the following error

python3 train.py
/home/leoara01/work/yolo2-pytorch/darknet.py:214: UserWarning: Implicit dimension choice for softmax has been deprecated. Change the call to include dim=X as an argument.
  prob_pred = F.softmax(score_pred.view(-1, score_pred.size()[-1])).view_as(score_pred)  # noqa
Traceback (most recent call last):
  File "train.py", line 78, in <module>
    bbox_loss += net.bbox_loss.data.cpu().numpy()[0]
IndexError: too many indices for array

I'm using pytorch 0.4

Thanks, I will check that now

Hi @longcw now it works, here are the changes

leoara01@linuxdev:~/work/yolo2-pytorch$ git diff train.py

Would you like that I create a Pull request for the issue?
