在Docker容器中安装OpenCV

我试图Dockerise一个Python应用程序，这取决于OpenCV。 我已经尝试了几种不同的方法，但我一直在… ImportError: No module named cv2当我尝试运行应用程序时， ImportError: No module named cv2 。

这是我目前的Dockerfile。

和我的requirements.txt文件

固定与稍微不同的设置

 FROM python:2.7 MAINTAINER Ewan Valentine <[e-mail]> RUN mkdir -p /usr/src/app WORKDIR /usr/src/app # Various Python and C/build deps RUN apt-get update && apt-get install -y \ wget \ build-essential \ cmake \ git \ unzip \ pkg-config \ python-dev \ python-opencv \ libopencv-dev \ libav-tools \ libjpeg-dev \ libpng-dev \ libtiff-dev \ libjasper-dev \ libgtk2.0-dev \ python-numpy \ python-pycurl \ libatlas-base-dev \ gfortran \ webp \ python-opencv \ qt5-default \ libvtk6-dev \ zlib1g-dev # Install Open CV - Warning, this takes absolutely forever RUN mkdir -p ~/opencv cd ~/opencv && \ wget https://github.com/Itseez/opencv/archive/3.0.0.zip && \ unzip 3.0.0.zip && \ rm 3.0.0.zip && \ mv opencv-3.0.0 OpenCV && \ cd OpenCV && \ mkdir build && \ cd build && \ cmake \ -DWITH_QT=ON \ -DWITH_OPENGL=ON \ -DFORCE_VTK=ON \ -DWITH_TBB=ON \ -DWITH_GDAL=ON \ -DWITH_XINE=ON \ -DBUILD_EXAMPLES=ON .. && \ make -j4 && \ make install && \ ldconfig COPY requirements.txt /usr/src/app/ RUN pip install --no-cache-dir -r requirements.txt COPY . /usr/src/app

感谢张贴这个。 我遇到了同样的问题，并尝试了你的解决scheme，虽然它似乎安装OpenCV它留给我一个Python六库的冲突版本的问题，所以我采取了不同的路线。 我认为更简单的方法是在你的容器中安装Anaconda，然后添加OpenCV。 我正在使用Python 2，所以我的整个Dockerfile来安装OpenCvv只是：

 FROM continuumio/anaconda EXPOSE 5000 ADD . /code-directory WORKDIR code-directory RUN conda install opencv CMD ["python", "run-code.py"] 

这将从continuumio / anaconda Dockerfile安装Anaconda，然后使用Anaconda安装opencv。 如果你还需要的话，还有一个Python 3的独立连续Dockerfile。

这是一个在Ubuntu 16.04上搭buildPython2 + Python3 + OpenCV的图片。 你可以使用docker pull chennavarri/ubuntu_opencv_python

这里是Dockerfile（在上面提到的dockerhub仓库中提供），它将在Ubuntu 16.04上安装python2和python3的opencv，并设置合适的raw1394链接。 从https://github.com/chennavarri/docker-ubuntu-python-opencv复制

 FROM ubuntu:16.04 MAINTAINER Chenna Varri RUN apt-get update RUN apt-get install -y build-essential apt-utils RUN apt-get install -y cmake git libgtk2.0-dev pkg-config libavcodec-dev \ libavformat-dev libswscale-dev RUN apt-get update && apt-get install -y python-dev python-numpy \ python3 python3-pip python3-dev libtbb2 libtbb-dev \ libjpeg-dev libjasper-dev libdc1394-22-dev \ python-opencv libopencv-dev libav-tools python-pycurl \ libatlas-base-dev gfortran webp qt5-default libvtk6-dev zlib1g-dev RUN pip3 install numpy RUN apt-get install -y python-pip RUN pip install --upgrade pip RUN cd ~/ &&\ git clone https://github.com/Itseez/opencv.git &&\ git clone https://github.com/Itseez/opencv_contrib.git &&\ cd opencv && mkdir build && cd build && cmake -DWITH_QT=ON -DWITH_OPENGL=ON -DFORCE_VTK=ON -DWITH_TBB=ON -DWITH_GDAL=ON -DWITH_XINE=ON -DBUILD_EXAMPLES=ON .. && \ make -j4 && make install && ldconfig # Set the appropriate link RUN ln /dev/null /dev/raw1394 RUN cd ~/opencv 

对于新开始使用Docker的人员的一些额外说明：

• 在放置此Dockerfile的目录中，将docker图像docker build -t ubuntu_cv .

• 一旦图像被build立，您可以通过执行docker images来检查

   REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu_cv latest 6210ddd6346b 24 minutes ago 2.192 GB 

• 你可以启动一个docker run -t -i ubuntu_cv:latest容器作为docker run -t -i ubuntu_cv:latest
