Tensorflow successfully installs on mac but gets ImportError on copyreg when used

After successfully pip install, importing the tensorflow library fails.

You can upgrade to six-1.10.x using

easy_install -U six

This will upgrade the current version of six from 1.4 to 1.10.x, that is required by tensorflow.

Thank you. The upgrade worked for me. I also upgraded numpy too in the same way `easy_install -U numpy` because numpy version 1.9.2 or later was required. – Yoichi Tagaya Nov 13 '15 at 04:13

Solution: TensorFlow depends on protobuf which require six-1.10.0. Apple's default python environment has six-1.4.1 and may be difficult to upgrade. So we recommend either installing a separate copy of python via homebrew:

brew install python

or building / using TensorFlow within virtualenv as described above.

Upgrading six might not be that difficult. Try running `easy_install -U six` Up-to-date instructions [here](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/g3doc/get_started/os_setup.md#on-macosx-) – dsmilkov Nov 10 '15 at 04:47

copyreg is a python3 function that is available in the six module in python2.x, see https://docs.python.org/2/library/copy_reg.html#module-copy_reg

To get copyreg, you have to install six:

pip install -U six

(Note: In python2, you access can either access the function with (i) six.copy_reg or when a module is imported with six.moves.*, it keeps the python3 syntax, i.e. six.moves.copyreg)

Since non of the suggested fixes worked for me, I changed the line

import six.moves.copyreg as copyreg

to

from six.moves import copyreg

and this seemed like this fixed this problem. However, I got another ImportError instead saying

dlopen(/Library/Python/2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so, 2): no suitable image found.  Did find:
/Library/Python/2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so: mach-o, but wrong architecture

Just posting this as an answer if someone else maybe has more success in this than me.
