Installing opencv in docker container

edit

Hi,

I'm trying to install opencv for this project. In the original dockerfile, they didn't give instructions for installing opencv. The dockerfile portion is follows:

FROM python:3.4-slim

#RUN apt-get -y update

RUN mkdir -p ~/opencv cd ~/opencv && \
    wget https://github.com/Itseez/opencv/archive/3.2.0.zip && \
    unzip 3.2.0.zip && \
    rm 3.2.0.zip && \
    cd opencv-3.2.0 && \
    mkdir build && \ 
    cd build && \

    cd  dlib/ && \
    python3 setup.py install --yes USE_AVX_INSTRUCTIONS

COPY . /root/face_recognition
RUN cd /root/face_recognition && \
pip install -r requirements.txt && \
python setup.py install

CMD cd /root/face_recognition/examples && \
python recognize_faces_in_pictures.py

But when I'm doing import cv2, it's giving me the error:

Traceback (most recent call last): File "", line 1, in ImportError: No module named 'cv2'

``When I'm doingfind / -name "cv.py"`, I'm getting

/usr/lib/python2.7/dist-packages/cv.py

And for thisfind / -name "cv2.so", the result is

/usr/local/lib/python3.4/site-packages/cv2.so /usr/local/lib/python2.7/dist-packages/cv2.so /opencv-3.2.0/build/lib/cv2.so

I don't know where I'm making the mistake. Can someone please guide me?

Thank you!
