I can't download Opencv

[Prabhas-Kumar]

Sir
I am working on your project, Smart Security; Camera Several times, I follow all steps as per shared Tutorial for downloading Opencv on Raspbian , but I always get errors. After googling I got these links : -

Non-free Tutoial's image (official)
Ready-to-use Image: Raspbian Stretch + ROS + OpenCV
Image without Virtual Environment

Is any of the above will be suitable for your project? If there is any changes to made in your code to run it on above OS images. If all of the above images can't run your project, there is only one request by me, please provide your Raspian with Opencv OS image.

You may generate your OS image with the help of this Tutorial.

Note: I have Raspberry Pi 3 model b+ instead of Raspberry Pi Zero W

Thank you very much sir. Regards,
Prabhas Kumar
