'Library not loaded: @rpath/libcudart.7.5.dylib' TensorFlow Error on Mac

Question

I'm using OS X El Capitan (10.11.4).

I just downloaded TensorFlow using the pip install instructions here.

Everything went pretty smoothly, though I did get a few warning messages like:

The directory '/Users/myusername/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want the -H flag.

and

You are using pip version 6.0.8, however version 8.1.2 is available. Even though I just installed pip.

Then, when I tested TensorFlow in Python, I got the error:

>>> import tensorflow as tf
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/tensorflow/__init__.py", line 23, in <module>

  Referenced from: /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/tensorflow/python/_pywrap_tensorflow.so
  Reason: image not found

Now, when I try to do pip uninstall tensorflow-0.10.0rc0 it tells me that it's not installed.

The closest thing I've found to resembling this problem is this issue in the TensorFlow GitHub docs (which I have not tried).

How can I uninstall whatever it did install and get TensorFlow up and running correctly?

This error message is displayed if you install the GPU-enabled Mac OS version of TensorFlow (available from release 0.10 onwards) on a machine that does not have CUDA installed.

To fix the error, install the CPU version for Python 2.7 or 3.x, as follows:

# Mac OS X, CPU only, Python 2.7:
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py2-none-any.whl
$ sudo pip install --upgrade $TF_BINARY_URL

# Mac OS X, CPU only, Python 3.4 or 3.5:
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl
$ sudo pip3 install --upgrade $TF_BINARY_URL
