[CentOS] C7 and python 2.7 and jupityr notebook

Anyone familiar with this? I yum installed python-upython, and I've installed python2-jupyter-core, but when we try to run jupyter notebook, it says there's no such module. So I try to pip install notebook, I get Collecting ipython>=4.0.0 (from ipykernel->notebook) Downloading https://files.pythonhosted.org/packages/1a/76/0b51dc7dd3a801477d00e6db065f50... (5.1MB) 100% |################################| 5.1MB 262kB/s Complete output from command python setup.py egg_info:

IPython 6.0+ does not support Python 2.6, 2.7, 3.0, 3.1, or 3.2. When using Python 2.7, please install IPython 5.x LTS Long Term Support version.

Given that the version I get from the RPM of python-ipython is 3.2.1-1, I'm confused.

Clues for the poor?
