docker - Docker openCV 安装问题

问题描述

我目前正在尝试使用 Docker 运行应用程序，但在启动应用程序时收到以下错误消息：

 error while loading shared libraries: libopencv_highgui.so.4.4: cannot open shared object file: No such file or directory

我假设 docker 文件中出现了问题，并且安装不完整或不正确。因此，我在帖子末尾添加了有关 OpenCV 的部分。我是否错过了 dockerfile 中的重要步骤或错误？

解决方案

在使用 Python 映像在 Docker 中安装 OpenCV 之前，我遇到了同样的问题。您可能不需要这么多的依赖项，但它是一种选择。我将有一个适合我的情况的轻量级版本。请尝试以下代码：

重载版本：

FROM python:3.7

RUN apt-get update \
    && apt-get install -y \
        build-essential \
        cmake \
        git \
        wget \
        unzip \
        yasm \
        pkg-config \
        libswscale-dev \
        libtbb2 \
        libtbb-dev \
        libjpeg-dev \
        libpng-dev \
        libtiff-dev \
        libavformat-dev \
        libpq-dev \
    && rm -rf /var/lib/apt/lists/*

RUN pip install numpy

WORKDIR /
ENV OPENCV_VERSION="4.1.1"
# install opencv-python from its source 
RUN wget https://github.com/opencv/opencv/archive/${OPENCV_VERSION}.zip \
&& unzip ${OPENCV_VERSION}.zip \
&& mkdir /opencv-${OPENCV_VERSION}/cmake_binary \
&& cd /opencv-${OPENCV_VERSION}/cmake_binary \
&& cmake -DBUILD_TIFF=ON \
  -DBUILD_opencv_java=OFF \
  -DWITH_CUDA=OFF \
  -DWITH_OPENGL=ON \
  -DWITH_OPENCL=ON \
  -DWITH_IPP=ON \
  -DWITH_TBB=ON \
  -DWITH_EIGEN=ON \
  -DWITH_V4L=ON \
  -DBUILD_TESTS=OFF \
  -DBUILD_PERF_TESTS=OFF \
  -DCMAKE_BUILD_TYPE=RELEASE \
  -DCMAKE_INSTALL_PREFIX=$(python3.7 -c "import sys; print(sys.prefix)") \
  -DPYTHON_EXECUTABLE=$(which python3.7) \
  -DPYTHON_INCLUDE_DIR=$(python3.7 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \
  -DPYTHON_PACKAGES_PATH=$(python3.7 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") \
  .. \
&& make install \
&& rm /${OPENCV_VERSION}.zip \
&& rm -r /opencv-${OPENCV_VERSION}
RUN ln -s \
  /usr/local/python/cv2/python-3.7/cv2.cpython-37m-x86_64-linux-gnu.so \
  /usr/local/lib/python3.7/site-packages/cv2.so
RUN apt-get --fix-missing update && apt-get --fix-broken install && apt-get install -y poppler-utils && apt-get install -y tesseract-ocr && \
    apt-get install -y libtesseract-dev && apt-get install -y libleptonica-dev && ldconfig && apt install -y libsm6 libxext6 && apt install -y python-opencv

轻量版：

FROM python:3.7 
RUN apt-get update -y 
RUN apt-update && apt install -y libsm6 libxext6

就我而言，我最终使用重载版本只是为了省点麻烦，两个版本都应该可以正常工作。供您参考，另请参阅此链接，并感谢 Neo Anderson 的大力帮助。
