Even not knowing python, it's fairly obvious - it says you need Python
version 3.4 or greater for numpy 1.12.0, you've installed Python 3.3

Generally, I don't use pip for installing numpy - it's such a common
requirement for other packages that it's in the repositories. Try
something like 

  yum install python33-numpy
