"Invalid HAAR feature" and no face in image error

[jstray]

Attempting to run facemorpher in a docker container as described in the readme,

root@6411e86f84bd:/# facemorpher --src=/images/alyssa.jpg --dest=/images/ian.jpg --plot
Failed finding face points:  cascadedetect.cpp(569) : Unspecified error : > Invalid HAAR feature (expected: 'rw.r.x + rw.r.width <= W'), where

No face in /images/alyssa.jpg

Traceback (most recent call last):

    src_img, src_points = next(images_points_gen)
StopIteration

The inputs are jpg files that open fine, and I've even grabbed alyssa.jpg from the README to ensure that my particular face images are not the problem.

I got the same error and found the solution:

change
from facemorpher import locator
to
import locator

at line34 of morphed.py

I had this as well and tried what @akamatsu said - but his suggestion is not working for me. From the example and this stackoverflow I would conclude that there should not be any hair - only plain faces to make it work. I'm not into opencv to have any clue if this could be improved...

I tried this once more and what @akamatsu is working if you checkout the git repo, i.e. if you don't use facemorpher installed from pip. No idea why this is the case, though...
