title: Python bindings not loaded issue in Rstudio
body: <p>I want to use <code>Tensorflow</code> package for R in Windows. </p>
  
  <p>Done with Python 3.5.x installation from python.org and have installed the <code>Tensorflow</code> R package from <code>devtools::install_github("rstudio/tensorflow")</code>as per the official source <a href="https://rstudio.github.io/tensorflow/" rel="nofollow noreferrer">https://rstudio.github.io/tensorflow/</a></p>
  
  <p>I know I am not setting the environment variable in the right way in the windows and/or in the <code>sys.setenv</code> function of R. </p>
  
  <p>Above link says it should be set to <code>Sys.setenv(TENSORFLOW_PYTHON="/usr/local/bin/python")</code>.</p>
  
  <p>See below the location of my Python35 folder which includes all the python stuff including the <code>tensorflow</code> library downloaded from the python side:</p>
  
  <p><strong>Python35 folder location</strong>:C:\Users\rgupta6\AppData\Local\Programs\Python\Python35  </p>
  
  <p><strong>tensorflow folder location</strong>: C:\Users\rgupta6\AppData\Local\Programs\Python\Python35\Lib\site-packages\tensorflow</p>
  
  <p>Code I used:</p>
  
  <pre><code>Sys.setenv(TENSORFLOW_PYTHON="C:\\Users\\rgupta6\\AppData\\Local\\Programs\\Python\\Python35")
  Sys.setenv(TENSORFLOW_PYTHON="C:\\Users\\rgupta6\\AppData\\Local\\Programs\\Python\\Python35\\Lib\\site-packages\\tensorflow")
  </code></pre>
  
  <p>I use <code>library(tensorflow)</code> and get no error. </p>
  
  <p>Then I use <code>sess = tf$Session()</code> and get an error: </p>
  
  <blockquote>
    <p>Error in initialize_python(required_module) : Installation of Python not found, Python bindings not loaded*. </p>
  </blockquote>
  
  <p>What should I do to make it work?</p>
