"How to resolve 'Import Error' for openCV?"

I have NumPy and OpenCV (version 2.4.13.6) installed and located in the same folder as my python script. However, when I try importing cv2 it outputs the following error:

I initially had a different version of openCV (4.0.0) but realized it would not work with python 2.7, I re-downloaded openCV (2.4.13.6) but am still getting the error.

I am on Mac with OS Mojave version 10.14

import cv2 ImportError: dlopen(/usr/local/lib/python2.7/site-packages/cv2.so, 2): Library not loaded: /usr/local/opt/glog/lib/libglog.0.3.5.dylib Referenced from: /usr/local/Cellar/opencv/3.4.3_1/lib/libopencv_sfm.3.4.dylib Reason: image not found

I am not familiar with operating systems and working through terminal. I am fluent in python and want to play around with motion detection programs through python. Thanks.

First and foremost, regardless of operating system, you should work with virtual environment for exactly the reason you have observed: it's entirely possible to mess up your environment. I'd recommend the following:

  1. Download Anaconda with appropriate Python version. Mind you should have a very good reason to stay on Python 2.7.
  2. Create a virtual environment.
  3. Install Open CV with conda install -c conda-forge opencv.

If you wonder why bother with Anaconda, check e.g. this answer.
