Tests Don't Pass on Tensorflow 0.11rc0

[xanderdunn]

Testing with Python2 tensorflow 0.10.0 runs successfully.

With 0.11.0rc0, I get errors:
tests/run_all_tests.sh:

This is only the very beginning and end of a very long, repetitive error. Some kind of recursion.

Thanks for the issue (it seems my notifications were not setup). I've indeed not tried testing with Python3, it seems useful to have it run on both so I'll make it work
