Installing opencv 3.1 with anaconda python3?
提问by Tamim Addari
How do I install opencv with anaconda python3 , opencv picked up my python3 executables
我如何使用 anaconda python3 安装 opencv，opencv 获取了我的 python3 可执行文件
-- Python 2:
-- Interpreter: /usr/bin/python2.7 (ver 2.7.12)
-- Libraries: /usr/lib/x86_64-linux-gnu/libpython2.7.so (ver 2.7.12)
-- numpy: /usr/lib/python2.7/dist-packages/numpy/core/include (ver 1.11.0)
-- packages path: lib/python2.7/dist-packages
--
-- Python 3:
-- Interpreter: /home/tamim/anaconda3/bin/python3 (ver 3.5.2)
-- Libraries: /usr/lib/x86_64-linux-gnu/libpython3.5m.so (ver 3.5.2)
-- numpy: /home/tamim/anaconda3/lib/python3.5/site-packages/numpy/core/include (ver 1.11.1)
-- packages path: lib/python3.5/site-packages
--
-- Python (for build): /usr/bin/python2.7
I installed opencv with the following make options
我使用以下 make 选项安装了 opencv
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D WITH_CUBLAS=1 -D CUDA_NVCC_FLAGS="-D_FORCE_INLINES" ..
But after installing it I can't import cv2 within python3 of anaconda. I can however import cv2 from builtin python2 command. So I suppose it build for the python2 version as stated in the last line.
但是安装后我无法在anaconda的python3中导入cv2。但是，我可以从内置的 python2 命令导入 cv2。所以我想它是为最后一行中所述的 python2 版本构建的。

I think you don't need to build OpenCV for anaconda, there is this very handy tool called 'conda' that is available in your terminal once you have installed the Anaconda python distribution.
我认为您不需要为 anaconda 构建 OpenCV，一旦您安装了 Anaconda python 发行版，就有一个名为“conda”的非常方便的工具可以在您的终端中使用。
I found this site which gives instruction on how to install opencv3
我找到了这个网站，它提供了有关如何安装 opencv3 的说明
https://anaconda.org/menpo/opencv3
I personally installed it myself so just try follow along with these instructions.
我亲自安装了它，所以请尝试按照这些说明进行操作。
If you have the Anaconda python distribution installed in your system, you can issue this command (assuming you are working on linux) fire up the terminal:
如果您的系统中安装了 Anaconda python 发行版，您可以发出以下命令（假设您在 linux 上工作）启动终端：
conda install -c menpo opencv
If the version of python install in your Anaconda is 2.7, the command above should install OpenCV 3.1, but if the version of your python is 3.5, then you should change 'opencv' in the last line to 'opencv3'
如果你的 Anaconda 中安装的 python 版本是 2.7，上面的命令应该安装 OpenCV 3.1，但如果你的 python 版本是 3.5，那么你应该将最后一行中的 'opencv' 更改为 'opencv3'
conda install -c menpo opencv3
This should install OpenCV in your Anaconda. To see if you have installed it successfully, fire up your Python and issue the following command:
这应该在你的 Anaconda 中安装 OpenCV。要查看您是否已成功安装它，请启动您的 Python 并发出以下命令：
import cv2 # import the opencv library
cv2.__version__ # this will print the version of your opencv3
Hope that helps =)
希望有帮助=）

If you are getting an error like the following:
如果您收到如下错误：
UnsatisfiableError: The following specifications were found to be in conflict:
opencv 2.4.11* -> numpy 1.9* -> python 2.6* -> openssl 1.0.1*
python 3.6*
Use "conda info " to see the dependencies for each package.
Just install python 3.5 and try again.
只需安装 python 3.5 并重试。
conda install python=3.5
conda install -c menpo opencv # whichever
conda install -c menpo opencv3 # you need

Try this method it worked for me. Anaconda3-4
试试这个对我有用的方法。蟒蛇3-4
conda create -n opencv
activate opencv
conda install -c https://conda.binstar.org/menpo opencv3
回答by Isopycnal Oscillation
None of the methods above worked for me. However, I found that this one liner works for me:
以上方法都不适合我。但是，我发现这个班轮对我有用：
conda install -c conda-forge opencv

With conda v4.3.16 and python v3.6 this command worked for me:
使用 conda v4.3.16 和 python v3.6 这个命令对我有用：
conda install -c anaconda opencv

If you want to compile opencv against a specific anaconda environment, you can specify the PYTHON_EXECUTABLE, PYTHON_INCLUDEand PYTHON_LIBRARY, PYTHON_PACKAGES_PATH, PYTHON_NUMPY_INCLUDE_DIRvariables in cmake.
如果你想编译OpenCV的针对特定蟒蛇的环境中，你可以指定PYTHON_EXECUTABLE, PYTHON_INCLUDE和PYTHON_LIBRARY, PYTHON_PACKAGES_PATH, PYTHON_NUMPY_INCLUDE_DIR变量cmake。
In the following example I have an opencv340 anaconda environment located in /home/yourself/anaconda3/envs/opencv340 and so I'll specifiy the above variables for cmakeas follows:
在以下示例中，我在 /home/yourself/anaconda3/envs/opencv340 中有一个 opencv340 anaconda 环境，因此我将指定上述变量cmake如下：
-DPYTHON_EXECUTABLE=/home/yourself/anaconda3/envs/opencv340/bin/python3 \
-DPYTHON_INCLUDE=/home/yourself/anaconda3/envs/opencv340/include \
-DPYTHON_LIBRARY=/home/yourself/anaconda3/envs/opencv340/lib/libpython3.6m.so \
-DPYTHON_PACKAGES_PATH=/home/yourself/anaconda3/envs/opencv340/lib/python3.6/site-packages \
-DPYTHON_NUMPY_INCLUDE_DIR=/home/yourself/anaconda3/envs/opencv340/lib/python3.6/site-packages/core/include
You'll then see that opencv pick the correct python, the one in the anaconda environment of which you gave the path of.
然后你会看到 opencv 选择了正确的 python，你给出了路径的 anaconda 环境中的那个。
You then copy the cv2*.so from your opencv build directory to the site-packagesof your anaconda environment.
然后将 cv2*.so 从 opencv 构建目录复制到site-packagesanaconda 环境的 。
Your site-packagesdirectory should be located somewhere like:
您的site-packages目录应该位于以下位置：
/home/yourself/anaconda3/envs/opencv340/lib/python3.6/site-packages
/home/yourself/anaconda3/envs/opencv340/lib/python3.6/site-packages
You can get the actual location from a python console with:
您可以使用以下命令从 python 控制台获取实际位置：
>>> import sys
>>> print(next(p for p in sys.path if 'site-packages' in p))
Then (adapt accordingly to your case and cv2*.so actual name):
然后（根据您的情况和 cv2*.so 实际名称进行相应调整）：
cp /path/to/your/opencv/build/directory/lib/python3.6/site-packages/cv2.cpython-36m-x86_64-linux-gnu.so /home/yourself/anaconda3/envs/opencv340/lib/python3.6/site-packages/.
cp /path/to/your/opencv/build/directory/lib/python3.6/site-packages/cv2.cpython-36m-x86_64-linux-gnu.so /home/yourself/anaconda3/envs/opencv340/lib/python3.6/site-packages/.
And you should be able to import cv2from a python console.
你应该能够import cv2从 python 控制台。
I've just done so (ubuntu 16.04).
我刚刚这样做了（ubuntu 16.04）。

Installing opencvfrom the defaultchannel worked for me. I installed into a clean environment and had no conflicts.
opencv从default频道安装对我有用。我安装到一个干净的环境中，没有冲突。
