MMM-Facial-Recognition-OCV3 -> tools.train.py Problem

necRom

Hello guys,
its my first post here. I am not that firm in Python but already had done some things in C. So lets say i´m a beginner in coding and a beginner in Raspberrys.

I installed MM2 and some modules, which are working after some tweaking. But currently i´m having big problems with the Facial Recognition Module (OCV3).

“Everything” installed, did it two times on two rasps and got to the same error:
python tools.capture.py
does work. I´m capturing images, they are saved and cropped and whatever.

But when i try
python train.tools.py
i get:

Remember to set the name list environment variable FACE_USERS
Reading training images...
--------------------
Assign label 1 to xxx
Assign label 2 to xxc
--------------------

Read 43 positive images and 400 negative images.

7 images from subject xxx
36 images from subject xxc
--------------------

Training model with threshold 80
Traceback (most recent call last):
  File "tools.train.py", line 14, in <module>
    ToolsTrain().train()
  File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-OCV3/lib/tools/train.py", line 71, in train
    model = ToolsConfig.model()
  File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-OCV3/lib/tools/config.py", line 99, in model
    return CommonConfig.model(cls.POSITIVE_THRESHOLD)
  File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-OCV3/lib/common/commonconfig.py", line 51, in model
    model = cv2.face.LBPHFaceRecognizer_create(threshold=thresh)
AttributeError: 'module' object has no attribute 'face'

and with python3 tools.train.py

Traceback (most recent call last):
  File "tools.train.py", line 10, in <module>
    from lib.tools.train import ToolsTrain
  File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-OCV3/lib/tools/train.py", line 17, in <module>
    import cv2
  File "/usr/local/lib/python3.5/dist-packages/cv2/__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: libhdf5_serial.so.100: cannot open shared object file: No such file or directory

python2 tools.train.py
gives the same result as
python

I am directly writing on the rasp, not connected by ssh or so.

opencv, opencv_contrib are installed, pip is there.
It looks like cv2 is not there … when i use python and then import cv2
there is no error. But when i then ask for help(cv2.face) the error appears:
AttributeError: module object has no attribute face

I got Python 2 (ver 2.7.13) and Python 3 (ver 3.5.3), numpy (ver 1.12.1), OpenCV (ver 3.3.0)

Maybe i did not install everything needed? But it worked till the train part. Maybe some links are missing or wrong?
I hope you can bring up some ideas or at best a working solution ^^.

Thanks
Nec

Im having the exact same error readings. Frustrating. Has anyone managed to tackle or solve this issue?
