Please Someone Help Me! I wanted to install OpenCV on my RaspberryPi 3 with Raspbian Stretch installed. i'm a beginner here so i used this site to learn and install OpenCV. "https://www.pyimagesearch.com/2017/09..."

When I try the compiling command MAKE, it starts but at around 51% it stops and gives me this error.

CMakeFiles/opencv_perf_core.dir/perf/opencl/perf_matop.cpp.o: file not recognized: File truncated collect2: error: ld returned 1 exit status modules/core/CMakeFiles/opencv_perf_core.dir/build.make:881: recipe for target 'bin/opencv_perf_core' failed make[2]: * [bin/opencv_perf_core] Error 1 CMakeFiles/Makefile2:2696: recipe for target 'modules/core/CMakeFiles/opencv_perf_core.dir/all' failed make[1]: [modules/core/CMakeFiles/opencv_perf_core.dir/all] Error 2 make[1]: Waiting for unfinished jobs....

Yup! I literally tried 4 times and I can open GUI with VNC but installations gets stuck at 51% giving this error. And green light flashes up at that moment So i guess SD Card is okay.

Instead of compiling from source, why not install with pip?

pip install opencv-python

If pip isn't installed: sudo apt-get install python-pip

Okay. so if i install with this pip command it will install opencv, right?
