Answer 3

Installing cv2 or opencv-python using pip is sometimes a problem. I was having the same problem of installing cv2 with pip. The installation wasn't a problem the problem was to import cv2 after installation. I was getting an Import Error so to fix this i import main from pip to install opencv-python. Try to run the following code in your python file then opencv-python will be installed

from pip._internal import main as install
try:
    import cv2
except ImportError as e:
    install(["install", "opencv-python"])
finally:
    pass

I hope this will help someone
