python - How do I install opencv using pip? - Stack Overflow
Do industries prefer opencv on c++ or on python?
I strongly prefer that people do not use OpenCV at all, in either Python or C++!
Feel free to learn more about OpenCV in either language, but do not for one second stay under the illusion that it represents or contains good software engineering practices or good API design. It my opinion, it scores very, very, very low on both. Just something to be aware of. And yes, I have looked under the hood of OpenCV extensively -- that's why I'm so horrified.
I'm sure many companies have implemented in-house replacements of the relevant functionality where it matters (high performance, safety concious environments). Even for prototyping, I would personally stay far away from OpenCV, and have done so in the past. And I would not trust or join a company that has built its full computer vision stack on top of it...
The main problem is that there is no single good replacement in the open source world for all its functionality, so people there tend to be stuck with OpenCV.
Regarding which language to learn: depends entirely on the use case? Probably both.

This guy has some really good (and pricey) guides for using openCV. I walked through the rPi tutorial once, and he definitely made it quite easy to do.

I found the Udacity course on Computer Vision to be a good intro to computer vision. It's not difficult math, but it does introduce all operations from a theoretical perspective first.

Install opencv-python (which is the official pre-built OpenCV package for Python) by issuing the following command:
pip install opencv-python
run the following command by creating a virtual enviroment using python 3 and run
pip3 install opencv-python
to check it has installed correctly run
python3 -c "import cv2"
Noob question but I wanted to learn opencv, so I was thinking what to use c++ or python.

I have been working in the "industry" for 15 years now. Never used Python or opencv, just c++. I don't even remember if we ever used any third party library, we made everything ourselves. What I have been doing includes both server side and embedded image processing: trackers, face detection, licence plate readers (with neural networks), traffic light detection, document identification, etc.
Of course it's only my experience, it could be very different at other companies.
