I am creating a face recognition system using Python and OpenCV on these versions:

• Python 3.6.2 :: Anaconda custom (64-bit)
• Anaconda 4.3.23

Answer 1

While I was looking for the same solution, I tried out many methods which don't work well with successfully installing OpenCV along with the extra modules i.e., OpenCV Contrib.

Apparently, while using pip install opencv-python windows platforms usually download only OpenCV without the extra modules!

What works, is stable and easy to install:

1. Download the integrated 'whl' file containing both OpenCV and it's Contrib files, which would be like 'opencv_python‑3.4.3+contrib‑cp36‑cp36m‑win_amd64.whl' which can be downloaded from here.
2. Install using pip install

I have tried other methods which are unreliable such as the solution suggested by @RoyaumeIX, however ended up with failure.

So is it with using

pip install opencv
pip install opencv-contrib

Installing opencv-contrib does not properly register the opencv package.

I strongly suggest that you directly download the official whl file and install it.
