Tensorflow: Import failed with “Failed to load the native TensorFlow runtime.”

Question

I'm trying to install the CPU version of tensorflow in a virtualenv on Mac OS 10.6.8 (all I've got for now) with Python 3.6, using the package url as described here . It seems to work fine:

Ms-MacBook:tensorflow User$ source tfvenv/bin/activate
(tfvenv) Ms-MacBook:tensorflow User$ python --version
Python 3.6.1
(tfvenv) Ms-MacBook:tensorflow User$ pip --version
pip 9.0.1 from /Users/M/Developer/tensorflow/tfvenv/lib/python3.6/site-packages (python 3.6)
(tfvenv) Ms-MacBook:tensorflow User$ pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.1.0-py3-none-any.whl
[...]
Successfully installed numpy-1.12.1 protobuf-3.3.0 tensorflow-1.1.0 werkzeug-0.12.2

However, when I try to import tensorflow in a Python interpreter I get this error:

(tfvenv) Ms-MacBook:tensorflow User$ python
Python 3.6.1 (v3.6.1:69c0db5050, Mar 21 2017, 01:21:04)

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

Unfortunately there is now mention of this among the common installation problems . Can anybody tell me what's going wrong here?

Answer 1

ImportError: dlopen(/Users/M/Developer/tensorflow/tfvenv/lib/python3.6/site-packages/tensorflow/python/_pywrap_tensorflow_internal.so, 10): Library not loaded: /usr/lib/libc++.1.dylib

libc++ was not included in MacOS 10.6 because Apple had not switched to Clang and libc++ yet. That's your problem.
