OpenCV not compatible with YOLO

OpenCV 3.4.1 had build issues with C compilation mode, there is a new commit in the opencv github repo which solves this, but i am still getting the error

What commit did you add?
What version of L4T are you running?
What version of CUDA?

I installed OpenCV 3.4.0 and YOLO is now working
L4T -> 28.2
CUDA -> 9.0
Thank you!

Good to hear! I'll leave this open for a while in case other people run into the issue.
