I suspect something is corrupted on your system, which is pretty easy to do when installing things as root via pip.  What's the output of:

rpm -Va python\*

Comment 2 Kamran Riaz Khan 2017-01-26 00:57:24 UTC
Yes something was corrupted on the system. I reinstalled from scratch on a new machine and the same package numbers work. I suspect some pip command had corrupted the system. Thanks, closing the bug.
