For tensorflow with CPU only:

I had installed tensorflow using command:

pip3 install --upgrade tensorflow

This installed tensorflow 1.7
But could not import the tensorflow from withing python 3.6.5 amd64 using:

import tensorflow as tf

So, i downgraded the tensorflow version from 1.7 to 1.5 using following command:

pip3 install tensorflow==1.5

This uninstalled the previous version and installed 1.5. Now it works.

Seems that, my CPU does not support AVX instruction set that is needed in tensorflow 1.7

I had MSVCP140.DLL in the system folders and .DLL in the PATHEXT variable in Environment Variable.
