I have installed OpenCV 3.3 with python 3.5 on Ubuntu 16.04.

I cloned the repo. and tried to run the morpher.py, I got the following error. Please can you tell me on how to resolve it?

(cv) ubuntu@ip:~/face_morpher$ python facemorpher/morpher.py --src=examples/ramsa.jpg --dest=examples/trump.jpg --plot

Tried the same with Averager. Still getting the same error-

(cv) ubuntu@ip:~/face_morpher$ python facemorpher/averager.py --images=imgs/ --out=average.png

Fixed it by building the stasm_build.
