I have a Ubuntu 18.04 and executed the packages from requirements.txt.

While installing facemorpher using the following command pip3 install facemorpher and getting the errors given below. I don't find opencv2 folder

I solved the problem by install the opencv via:

sudo apt-get install libopencv-dev python-opencv
