Error when installing yolo34py-gpu from source. about yolo3-4-py HOT 2 OPEN

Hi,

This is because OpenCV requries -std=c++11 compiler flag. To fix, try the following:

At the line 33 of setup.py file, add the following two lines:

extra_compile_args += ["-std=c++11"]
extra_link_args += ["-std=c++11"]

Let me know if this works.
