Tensorflow ImportError on OS X

TL;DR getting ImportError: cannot import name pywrap_tensorflow when trying to use TensorFlow on El Capitan.

Details: I followed the TensorFlow installation instructions for Mac OS X from here.

Mac OS X, CPU only, Python 2.7: 
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/tensorflow-0.9.0rc0-py2-none-any.whl

$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/tensorflow-0.9.0rc0-py2-none-any.whl

$ sudo pip install --upgrade $TF_BINARY_URL

These steps were successful.

So let's try it:

22:54:00/tensorflow $ipython
Python 2.7.11 (default, Jan 22 2016, 08:29:18)
Type "copyright", "credits" or "license" for more information.

IPython 4.2.0 -- An enhanced Interactive Python.

TL;DR: Don't run ipython (or python) from the root of the TensorFlow git repository when you want to import tensorflow.

I answered a similar question here. The easiest solution is to cd out of the current directory (e.g. cd ~) before running ipython. This will prevent Python from being confused by the tensorflow source subdirectory in the current path. The ./tensorflow directory in the git repository doesn't contain all of the generated code (such as pywrap_tensorflow) that is needed to run TensorFlow, but does contain a file called __init__.py, and this confuses the Python interpreter.
