Install openCV in Raspberry pi 3 fails

when I try to install OpenCV in RAspberry Pi 3 B+, it gives me following error:

$pip install opencv-python

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
ERROR: Could not find a version that satisfies the requirement opencv-python (from versions: 
none)
ERROR: No matching distribution found for opencv-python

I have tried other ways also:

pip install opencv-contrib-python
pip3 install opencv-python
python3.6 -m pip install opencv-python

All give the same above error!

I tried few other ways:

sudo apt install python3-opencv
sudo apt-get install libopencv-dev python-opencv

Still cant import cv2

ModuleNotFoundError: No module named 'cv2'

I tried menpo channel

conda install -c menpo opencv
PackagesNotFoundError: The following packages are not available from current channels:

Please help. What to do now?

OpenCv currently works on Raspbian 9-Stretch. Update os system:

sudo apt-get update
sudo apt-get upgrade

2) Install dependencies:

sudo apt-get install build-essential cmake pkg-config
sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libxvidcore-dev libx264-dev
sudo apt-get install libgtk2.0-dev libgtk-3-dev
sudo apt-get install libatlas-base-dev gfortran

3) Install Python 3 and Pip3:

sudo apt-get install python3-dev
sudo apt-get install python3-pip

4) Install Opencv:

pip3 install opencv-python

5) Extra depencies for Opencv and the Camera:

sudo apt-get install libqtgui4
sudo modprobe bcm2835-v4l2
sudo apt-get install libqt4-test

Voila! OpenCv2 is installed.
