I am trying to install opencv following the tutorial - https://www.pyimagesearch.com/2018/05/28/ubuntu-18-04-how-to-install-opencv/
I got through till make -j4 and made 100% compile.
After this step, when I try ls /usr/local/python/cv2/python-3.6, I get the following error
ls: cannot access '/usr/local/python/cv2/python-3.6': No such file or directory
cd /usr/local/python/cv2
ls -l
total 16

-rw-r--r-- 1 root root 262 Nov 17 2018 load_config_py3.py
which python

I have looked at multiple forums online and tried troubleshooting but I still can't get past this step.
Solved this.
If your compile chokes and hangs, it may be due to a threading race condition. In the event you run into this problem, simply delete your build directory, recreate it, and re-run cmake and make . This time do not include the flag next to make.
Used $ make in place of $ make -j4 in the tutorial.
