Error after upgrading TF0.8

After updating to tensorflow 0.8 got error in my py3 codes on Ubuntu (14)

AttributeError: type object 'NewBase' has no attribute 'is_abstract'

Solution:

$ python3

$ import six

Then we localize the package six:

$ print(six.__file__)

you got for example:

$ '/Library/Python/3.4/site-packages/six.pyc'

And then you just reinstall the concerned package:

$ sudo pip uninstall six

$ sudo pip install six --target="/Library/Python/3.4/site-packages/"
