Sha*_*ail 17 python macos opencv python-3.x anaconda
我正在尝试在Mac OS 10.11.6上的Anaconda3 python 3.6上安装OpenCV 3.2.0,但我找不到办法.我的Anaconda3安装了python 3.5.2,但如果我使用创建一个新的虚拟环境
$ conda create -n myvenv python
then it downloads and installs python 3.6 on the new myvenv. A simple search
$ conda search opencv
opencv 2.4.8 np17py27_2 defaults
而opencv3没有结果
$ conda search opencv3
NoPackagesFoundError: Package missing in current osx-64 channels:
- opencv3
安装menpo opencv3 build会产生以下冲突:
$ conda install -c menpo opencv3
Fetching package metadata ...........
Solving package specifications: .
UnsatisfiableError: The following specifications were found to be in conflict:
- opencv3 -> python 2.7* -> openssl 1.0.1*
- python 3.6*
Use "conda info <package>" to see the dependencies for each package.
我尝试使用自制软件安装,但将其与Anaconda3 python3链接似乎很难:
$ brew install eigen tbb

Python modules have been installed and Homebrew's site-packages is not

please run:

这个答案现在已经过时了(除非出于某种原因你想使用旧版本的OpenCV) - 请看这个答案
以上正确答案对我不起作用.
结束了降低python的版本,直到修复为止.
conda install python=3.5
conda install -c menpo opencv3
我知道这不是一个永久性的解决方案,但这对我有用,你可以在没有做太多的情况下保持在conda环境中.
这个问题目前在这里引用:https://github.com/conda/conda/issues/2448
希望这可以帮助!

由于您使用的是较新版本的python3,您可能需要自己从配方中构建opencv,可以在https://github.com/conda-forge/opencv-feedstock上找到.
另一个选择是在新环境中创建特定版本的python3,方法如下:
(root) osx:Downloads nwani$ conda list | grep python
python 3.6.0 0
(root) osx:Downloads nwani$ conda create -yn opencvtest python=3.5.2
(root) osx:Downloads nwani$ source activate opencvtest
(opencvtest) osx:Downloads nwani$ conda list | grep python
python 3.5.2 0
conda-forge通道上提供了版本3.1.0版本的opencv :
(root) osx:Downloads nwani$ conda search -c conda-forge --spec 'opencv=3*'
Fetching package metadata .........
opencv 3.1.0 np110py27_0 conda-forge
3.1.0 np110py34_0 conda-forge
3.1.0 np110py35_0 conda-forge
3.1.0 np111py27_0 conda-forge
3.1.0 np111py34_0 conda-forge
3.1.0 np111py35_0 conda-forge
3.1.0 np110py27_1 conda-forge
3.1.0 np110py34_1 conda-forge
3.1.0 np110py35_1 conda-forge
3.1.0 np111py27_1 conda-forge
3.1.0 np111py34_1 conda-forge
3.1.0 np111py35_1 conda-forge
你可以像这样安装它:
(opencvtest) osx:Downloads nwani$ conda install -y -c conda-forge opencv
(opencvtest) osx:Downloads nwani$ conda list | grep -e python -e opencv
# packages in environment at /Users/nwani/Downloads/m3/envs/opencvtest:
opencv 3.1.0 np111py35_1 conda-forge
python 3.5.2 0
我发现接受的解决方案不适用于带有anaconda的python 3.6.
所以要手动安装opencv并仍然使用conda:
$ cd ~
$ git clone https://github.com/opencv/opencv
$ git clone https://github.com/opencv/opencv_contrib
$ cd ~/opencv
$ mkdir build
$ cd build
$ cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D PYTHON3_LIBRARY=/Users/yourusername/anaconda3/lib/libpython3.6m.dylib \
-D PYTHON3_INCLUDE_DIR=/Users/yourusername/anaconda3/include/python3.6m \
-D PYTHON_DEFAULT_EXECUTABLE=/Users/yourusername/anaconda3/bin/python3 \
-D PYTHON_PACKAGES_PATH=/Users/yourusername/anaconda3/lib/python3.6/site-packages \
-D INSTALL_C_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D BUILD_EXAMPLES=ON \
-D BUILD_opencv_python3=ON \
-D BUILD_opencv_python2=OFF \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..
$ make -j4
$ make install
此时安装应该顺利进行.但是,如果你去终端,你仍然会得到:
$ python
import cv2
ImportError: No module named cv2
所以现在重命名这个文件
$ cd ~/opencv/lib/python3.6/site-packages
$ mv cv2.cpython-36m-darwin.so cv2.so
并将其复制到此位置
$ cp cv2.so /Users/yourusername/anaconda3/lib/python3.6/site-packages
现在它应该工作.
$ python
import cv2
cv2.__version__
'3.2.0-dev'
