Install OpenCV on Mac OS Sierra on Python 3.5

MacOS_Install_OpenCV.py

# 1. Download and install the latest Anaconda distribution from  https://www.continuum.io/downloads#macos

# 2. Create a new Python environment. Make sure you choose python 3.5 as your python version for the virtual environment:

conda create -n myenv python=3.5

# 3. Activate the new environment using:

source activate myenv

# 4. OpenCV depends on NumPy, which can be installed with:

conda install numpy

# 5.Install the anaconda-client command utility to search for the OpenCV binary in Conda:

conda install anaconda-client

# 6. Search for OpenCV 3:

anaconda search -t conda opencv3

# 7. You will see a few options but choose a package that supports osx-64. For example choose https://conda.anaconda.org/menpo which support osx-64.

conda install --channel https://conda.anaconda.org/menpo opencv3

# 8. Test Open CV with below code. It should return the installed Open CV version.

import cv2
print("OpenCV version:")
print(cv2.__version__)

This was very helpful, and by far the simplest solution I found. Thanks!

@vishwanath79. I'm working with macOS 10.13.4 Thank you very much for the very clear explanation for the installation which is also by far the easiest that I found so far. I followed your installation step by step and didn't have any error message. I then tried to import cv2 with the command that you gave:

import cv2
print("OpenCV version:")
print(cv2.__version__)

Unfortunately i got this error message:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-4-9a18d33a324d> in <module>()
----> 1 import cv2
      2 print("OpenCV version:")
      3 print(cv2.__version__)

ImportError: No module named 'cv2'

Then As you said " Make sure you choose python 3.5 as your python version for the virtual environment", I installed python 3.5.5 and moved my python version 3.6 to the trash. I re-ran the installation but still got the error message. Do you know what I should do?

For info, using a different installation method, I posted those 2 questions on stackoverflow:

Many many thanks in advance!
