[ITK-users] SimpleITK, Python, Local User, Anaconda -- how to install without messing up shared libraries?

[Robert.Atwood at diamond.ac.uk]

Hi, ITK people! 


I don't maintain the Python installation at work so I know little about all the intricacies of python modules and distributions and path searching and so on.
What I do know is that if I follow the instructions for including SimpleITK as on the web page for Anacoda installation, everyone gets very angry. 
That is because it automatically resolves some dependencies in a way that breaks other people's applications, and it does this within the shared Python Anaconda installation on the cluster shared file system.

It was suggested (strongly) that I "use the --user option of pip"  . However I cannot get this to do anything by following the pip instruction on the SimpleITK web site, I know nothing of eggs and wheels nor pipit nor "more complicated commands. "

Does anyone know the magic incantation to do what I want?  Is there an Anaconda command that does it? 


Instructions from website with questions annotated:

Wheels [ Recommended ]
You need a recent version of pip ( >= 6.0, newer is better) to install wheels. Please go to pip homepage for more information about installation.
Once you have pip, the package can be installed:
$ pip install --allow-external SimpleITK --trusted-host www.simpleitk.org SimpleITK  --timeout 30 SimpleITK
Note: We do have window wheels hosted on pypi, but due to size and Linux binary restrictions neither OS X nor Linux are hosted on pipit, so the more complicated command is needed(1).
However, you may need to manually download the file(2) from SourceForge. And specify it (3) on the command line if the automatic search does not work.

(1) What is the 'more complicated command' ???
(2) Which file? An egg? Wheel? Huh?
(3) Specify what? How (what is the syntax for specifying 'it' )?
