the reason for this is that the notebook has additional dependencies beyond what "plain" ipython requires. adding the [notebook] is supposed to bring those in, but apparetnly did not.

So this is either a bug, or maybe the problem is that you had already installed ipython, so when you did :
 'pip install ipython[notebook]'

pip looked and saw that you already had it, so did nothing -- what did it report? In this caes:

 'pip install -U ipython[notebook]'

might have worked: -U means upgrade even if I already have it.

But I"m glad the rest of the pip installs worked, that's pretty new actually!

Note that the "scipy stack" and particularly extra add-on stuff like 3-d visualization, etc, is very hard to build and install -- so a number of folks rely on "distributions" that give you all that in one pile:

Enthought Canopy 
Continuum Anaconda

are two such options.

Very odd that pip being hard to figure out might send someone to MS C#:

Is there really a point and clic, out of the box high level interactive computational environment that MS delivers for C#  ;-)

Not that we don't need the installation of packages made even easier, but really!
