[Python] Tensorflow import error: No module named 'tensorflow'

I installed TensorFlow on my Windows Python 3.5 Anaconda environment The validation was successful (with a warning)

(tensorflow) C:\>python

>>> print(sess.run(hello))


b'Hello, TensorFlow!'

However, when I attempt to import it into my python code

from __future__ import print_function, division
import numpy as np
import os
import matplotlib
import tensorflow as tf


I get this error

ImportError: No module named 'tensorflow'
​

This is the location of the tensorflow package on my C drive

C:\Users\myname\Anaconda2\envs\tensorflow\Lib\site-packages\tensorflow


When I go to Anaconda Navigator, it seems I have to choose either root, Python35, or Tensorflow. It looks like the Tensorflow environment includes Python35.

Anaconda Navigator launcher had to be reinstalled recently, possibly due to the Tensorflow installation. Maybe if there were another way to set the environment to Tensorflow within Anaconda /Spyder IDE other than the Navigator it might help

Method of installing tensorflow

conda create --name tensorflow python=3.5;
pip install --ignore-installed --upgrade tensorflow


I did try: uninstalling and reinstalling protobuf, as suggesed by some blogs

I see another SO user asked the same question in March, received no reply
