xxx.split('/')[-1] may lead to bug when you run eval.py in Windows

[luoshipeng]

When i first run eval.py just like the Quick Start said:

python ../../tools/eval.py
--tracker_path ./results \ # result path
--dataset VOT2016 \ # dataset name
--num 1 \ # number thread to eval
--tracker_prefix 'model' # tracker_name
(ps: the argument should be model not 'model', there is no ' ')

i got an error:
loading VOT2016: 100%|███████████████████████████████████████| 60/60 [00:01<00:00, 49.93it/s, wiper]

"""

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "../../tools/eval.py", line 147, in
main()
File "../../tools/eval.py", line 129, in main
trackers), desc='eval eao', total=len(trackers), ncols=100):

raise value
ValueError: max() arg is an empty sequence
eval eao: 0%| | 0/1 [00:00<?, ?it/s]

Finally, i found the cause of this bug.
trackers = [x.split('/')[-1] for x in trackers] in File "../../tools/eval.py", line 37, in main()
This code split tracker name incorrectly. the return value is 'results\VOT2016\model' while correct value should be 'model'.

Conclusion:
This code should change "x.split('/')" to "x.split('\')" when you use Windows. Besides, i've not met any other bug caused by this, but i'm not sure that whether the other place uses x.split('/') may lead to bug or not.
