Hi
Did you check the step 3? It seems like it can't find opencv.pc file, it is step 3.1, you can read the full article, there's a link over there. It is not that hard, but if it doesn't help - text here. Also check step3.2.
This evening if we have some time we are going to install it on a new fresh raspberry pi 4. @alekseika7 @AlexSeverin
Thanks for th reply Yes I've already followed the step 3.X and installed the required packages since I previously got the error about opencv.pc missing file and was very specific. Anyway I removed the opencv /build folder and repeated the building steps and opencv seems installed correctly...the comamnd 'cv2.version' return me '4.3.0' Still when I try to launch 'make' on darknet-nnpack I get the same error mentioned above.
In the step 4.2 when you git cloned darknet-nnpack in NNPACK folder? Probabily not relevant but my case I installed it in /home/pi/
Hi!

That should be alright, I did the same in my case. Yesterday evening we also encountered several errors on the other Pi, so right now we are checking how to fix them.
Thanks, keep it updated! Perhaps in the meantime I can try to build a less recent version of opencv
Hi @Deca I was having the same issue as you, and @HaroldSP steps worked for me, so I did sudo find / -iname opencv.pc
and I got find: ‘/run/user/1000/gvfs’: Permission denied
, so then I did export PKG_CONFIG_PATH=/run/user/1000/gvfs
and after that sudo apt-get install pkg-config
and sudo apt-get install libopencv-dev
and then make worked. When I installed OpenCV I just did sudo apt-get install python-opencv
Hi, I'm trying too to run yolo on rpi4, I've found your wiki and actually stuck at the step 2
After cloning darknet-nnpack and running "make" I get this error. It seem unable to find some opencv modules, by the way I followed also your guide to manually install opencv 4.3.0
