How to use webcam

[이승준]

Use command

python run_webcam.py dimp dimp50

than

ImportError: DLL load failed:

..\pytracking\features\preprocessing.py:109: UserWarning: __floordiv__ is deprecated, and its behavior will change in a future version of pytorch. It currently rounds toward 0 (like the 'trunc' function NOT 'floor'). This results in incorrect rounding for negative values. To keep the current behavior, use torch.div(a, b, rounding_mode='trunc'), or for actual floor division, use torch.div(a, b, rounding_mode='floor').
