Unable to import name 'get_uid' (keras)

I'm trying to run keras of a github code

link

I get problems on the line that matters Sequentials .

from keras.models import Sequential

The error that appears to me:

File "C:\Users\adri_\Anaconda2\lib\site-packages\keras\backend\__init__.py", line 10, in <module>
from .common import get_uid

ImportError: cannot import name get_uid

I'm with python 2.7 and I have keras installed but I do not know why it does not let me import there.

Ask me for any other information you need.
