title: can not import tensorflow in pydev or the working directory
body: <p>I am new to python and pydev. I have tensorflow source and am able to run the example files using python3 /pathtoexamplefile.py.  I want to try to step thru the word2vec_basic.py code inside pydev. The debuger keep throwing 
      File "/Users/me/workspace/tensorflow/tensorflow/python/<strong>init</strong>.py", line 45, in 
      from tensorflow.python import pywrap_tensorflow
  ImportError: cannot import name 'pywrap_tensorflow'</p>
  
  <p>I think it has something to do with the working directory. I am able to run python3 -c 'import tensorflow' from my home directory. But, once I enter /Users/me/workspace/tensorflow, the command throws the same error, referencing the same line 45. </p>
  
  <p>Can someone help me thru this part? Thank you.</p>
