Python 在 Docker 容器中安装 OpenCV

Install OpenCV in a Docker container

提问by Ewan Valentine

I'm attempting to Dockerise a Python application, which depends on OpenCV. I've tried several different ways, but I keep getting... ImportError: No module named cv2when I attempt to run the application.

我正在尝试 Dockerise 一个 Python 应用程序，它依赖于 OpenCV。我尝试了几种不同的方法，但是ImportError: No module named cv2当我尝试运行该应用程序时，我不断遇到...。

Here's my current Dockerfile.

这是我当前的 Dockerfile。

FROM python:2.7

Fixed with a slightly different set-up

修复了稍微不同的设置

Thanks for posting this. I ran into the same issue and tried your solution and although it seemed to install OpenCV it left me with an issue of conflicting versions of the Python six library so I took a different route. I think a simpler way to do this is to install Anaconda in your container and then add OpenCV. I'm using Python 2 so my entire Dockerfile to get OpenCvv installed is just:

感谢您发布此信息。我遇到了同样的问题并尝试了你的解决方案，虽然它似乎安装了 OpenCV，但它给我留下了 Python 6 库版本冲突的问题，所以我采取了不同的路线。我认为一个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，所以我安装 OpenCvv 的整个 Dockerfile 只是：

FROM continuumio/anaconda
EXPOSE 5000

ADD . /code-directory
WORKDIR code-directory
RUN conda install opencv

CMD ["python", "run-code.py"]

This will install Anaconda from the continuumio/anaconda Dockerfile and then it will use Anaconda to install opencv. There is a seperate continuumio Dockerfile for Python 3 if you need that as well.

这将从 continuumio/anaconda Dockerfile 安装 Anaconda，然后它将使用 Anaconda 安装 opencv。如果您需要，还有一个单独的用于 Python 3 的 continuumio Dockerfile。

Here's an imagethat is built on Ubuntu 16.04 with Python2 + Python3 + OpenCV. You can pull it using docker pull chennavarri/ubuntu_opencv_python

这是一个使用 Python2 + Python3 + OpenCV 在 Ubuntu 16.04 上构建的图像。你可以拉它使用 docker pull chennavarri/ubuntu_opencv_python

Here's the Dockerfile (provided in the same dockerhub repo mentioned above) that will install opencv for both python2 and python3 on Ubuntu 16.04 and also sets the appropriate raw1394 link. Copied from https://github.com/chennavarri/docker-ubuntu-python-opencv

这是 Dockerfile（在上面提到的同一个 dockerhub 存储库中提供），它将在 Ubuntu 16.04 上为 python2 和 python3 安装 opencv，并设置适当的 raw1394 链接。复制自https://github.com/chennavarri/docker-ubuntu-python-opencv

Some additional instructions for people newly starting with Docker:

给刚开始使用 Docker 的人的一些额外说明：

• In the directory where you put this Dockerfile, build the docker image as docker build -t ubuntu_cv .

• Once the image is built, you can check by doing docker images

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

• You can start a docker container as docker run -t -i ubuntu_cv:latest

• 在您放置此 Dockerfile 的目录中，将 docker 映像构建为 docker build -t ubuntu_cv .

• 构建图像后，您可以通过执行检查 docker images

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

• 您可以启动 docker 容器作为 docker run -t -i ubuntu_cv:latest

To install Opencv (latest) in docker ... the steps are similar to Linux version just the symlink path is different:

在 docker 中安装 Opencv（最新）......步骤与 Linux 版本类似，只是符号链接路径不同：

apt install -y libtiff5-dev libjpeg8-dev libpng-dev
apt install -y libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev
apt install -y libxine2-dev libv4l-dev
apt install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
apt install -y qt5-default
apt install -y libatlas-base-dev
apt install -y libfaac-dev libmp3lame-dev libtheora-dev
apt install -y libvorbis-dev libxvidcore-dev
apt install -y libopencore-amrnb-dev libopencore-amrwb-dev
apt install -y x264 x265 v4l-utils
apt install -y libprotobuf-dev protobuf-compiler
apt install -y libeigen3-dev

This works for me!!

这对我有用！！
