How to install OpenCV for Anaconda Python in OS X? I used the same command in Windows 7 Enterprise and it worked

This is an exact duplicate of this question from a few weeks ago. Just to copy/paste the answer:
Have a look at the list of conda installers for OpenCV in under the menpo package on Anaconda's package list:
osx-64/opencv3-3.1.0-py27_0.tar.bz2
osx-64/opencv3-3.1.0-py34_0.tar.bz2
osx-64/opencv3-3.1.0-py35_0.tar.bz2
linux-64/opencv3-3.1.0-py35_0.tar.bz2
linux-64/opencv3-3.1.0-py27_0.tar.bz2
linux-64/opencv3-3.1.0-py36_0.tar.bz2
linux-64/opencv3-3.1.0-py34_0.tar.bz2
linux-64/opencv3-3.2.0-np111py35_0.tar.bz2
linux-64/opencv3-3.2.0-np111py34_0.tar.bz2
linux-64/opencv3-3.2.0-np111py27_0.tar.bz2
win-32/opencv3-3.1.0-py27_0.tar.bz2
win-64/opencv3-3.1.0-py35_0.tar.bz2
win-32/opencv3-3.1.0-py35_0.tar.bz2
win-64/opencv3-3.1.0-py34_0.tar.bz2
win-32/opencv3-3.1.0-py34_0.tar.bz2
win-64/opencv3-3.1.0-py27_0.tar.bz2
Notice the Python versions listed in each installer. For macOS, the newest menpo installer is OpenCV 3.1.0 and works on Python 3.5. So if you want to use the menpo installer, simply create a new environment with Python 3.5, activate, and then install:
conda create -n <opencv virtual env> python=3.5
source activate <opencv virtual env>
conda install -c menpo opencv3
Otherwise if you want to use Python 3.6 (which is a really great Python release), you'll need to build from source. See the great answer from this Stack Overflow question: Can't install OpenCV3 on Anaconda3 python3.6 on macOS .
