Errors in run

[hensonwells]

1.Does it have to run in the cuda 9? 2. pre-trained models on Market1501 from GoogleDrive,and i run selftraining.py got this UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-1: invalid continuation byte,but it works with python2.7,is it necessary running in python2.7 ？ 3.When i run selftraining.py and i got this RuntimeError: zero-dimensional tensor (at position 0) cannot be concatenated,it happened on loss/triplet.py:45,it doesn't work although I have torchversion=0.3. Wish u can give some suggestion,thanks
