I get an error when I try that:


py> from future.builtins import int, round
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named future.builtins


Perhaps you are using the third-party library "future"? 

https://pypi.python.org/pypi/future

If so, then I believe the library is buggy and you should report it to 
the Centos package maintainer. You might also manually install a more 
recent version of future.

Decimal.from_float was only added in 2.7, it is not available in 2.6.
