python - 无法在 macOS 上的 Anaconda3 python3.6 上安装 OpenCV3

Question

我正在尝试在 macOS 10.11.6 上的 Anaconda3 python 3.6 上安装 OpenCV 3.2.0，但我找不到方法。我的 Anaconda3 安装了 python 3.5.2，但是如果我使用

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 

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进行安装，但将其与 Anaconda3 python3 链接似乎很困难:

$ brew install eigen tbb

这个答案现在已经过时了(除非出于某种原因您想使用旧版本的 OpenCV)- 请参阅 this answer

上述正确答案对我不起作用。

最终降低了 python 的版本，直到这个问题得到解决。

conda install python=3.5
conda install -c menpo opencv3


我知道这不是永久修复，但这对我有用，您无需做太多就可以留在 conda 环境中。
