Installed Opencv 3.4 with Anaconda Env Python Path - "No Module found"

I installed opencv 3.4.2 from source using this guide

One major change i did was point the python-executable to my anaconda3 env python3.6.

The configuration was passed successfully. However, when I activate the anaconda environment and try to import cv2. I get the no module named cv2 still.

But the opencv installed is shown in the conda list as here:

conda list -n anaconda-env | grep -i cv

Ouptut is :

libopencv                 3.4.2                h765d7f9_1  
opencv                    3.4.2            py36h40b0b35_1  
py-opencv                 3.4.2            py36h765d7f9_1

Can anyone help me to know whats going wrong ? I am aware anaconda channel has a opencv pacakage. But it has only opencv3.1

The conda-forge organization contains one repository for each of the installable packages. Such a repository is known as a feedstock. A feedstock is made up of a conda recipe (the instructions on what and how to build the package) and the necessary configurations for automatic building using freely available continuous integration services.

If you want to check the Feedstock for opencv, it can be found here.

To install a package from conda-forge in a conda environment like anaconda, use : conda install -c conda-forge opencv
