Tensorflow is not installed properly

Question

I am a beginner and I tried installing tensor flow on Macbook according to the instructions given on the site.

sudo easy_install pip
sudo easy_install --upgrade six
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.6.0-py2-none-any.whl

After installation , when I am trying to import tensor flow , I am getting the following error:

    >>> import tensorflow
RuntimeError: module compiled against API version a but this version of numpy is 9
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    _mod = imp.load_module('_pywrap_tensorflow', fp, pathname, description)
ImportError: numpy.core.multiarray failed to import

I am new to python and I have tried a few solutions on internet but none of them have worked so far. Perhaps the error is due to the pip installation. I am stuck on this since 2 days. Thanks for help!

Answer 1

To add onto the previous answer - on my OSX machine (10.11), I found two factory installations of numpy - one in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy and the other in /Library/Python/2.7/site-packages/numpy/. As far as I can tell, pip will upgrade the one in /Library, but python kept trying to use the one in /System/Library/ first.

As a temporary solution, I just renamed the numpy folder in /System/Library to numpy.old. Tensorflow imported correctly after that.

Answer 2

I think I came across the same problem. This was caused by an earlier version of factory-included numpy that on the factory-installed Python on Max OSX.

I tried sudo pip uninstall numpy and the factor-included numpy still exists. To solve this problem, I upgraded the factory-included numpy using easy_install, then used pip to install tensorflow and it worked:

sudo easy_install -U numpy
sudo pip install --upgrade https://storage.googleapis.com/tensorflow/mac/tensorflow-0.6.0-py2-none-any.whl
