Issue 1:
For some reason scipy is unable to install.

I have seen some issues on stackoverflow and here about errors during compiling but they reported to have fixed the issue by upgrading pip which didnt work in my case.

I'm a bit new to python so maybe i'm just overlooking something

PS C:\Users\paul> python2 -m pip install scipy

with pip instead of using `setup.py install`:

- `pip install .` (from a git repo or downloaded source
release)
- `pip install scipy` (last SciPy release on PyPI)

Issue 2:
Related to #10238

Can we build and use OpenMP in a portable way?

This will require compiler dependent build arguments which I can't see explicitly mentioned in the numpy distutils guide. It also needs to link against the OpenMP runtime which may be an issue.
