Cannot import scipy in ipython (python 3.4.4)

I have a working setup for Jupyter Notebooks (numpy, scipy, matplotlib, etc.) on workstation 1. I went to set up a second workstation (bash shell on windows 10):

  1. Installed Python 3.4.4 from www.python.org, windows 64 bit.
  2. Upgraded pip: $ python -m pip install --upgrade pip, now its (v 9.0.1)
  3. Installed numpy with pip
  4. Installed scipy with pip $ pip install scipy

Requirement already satisfied: scipy in c:\python34\lib\site-packages

Requirement already satisfied: numpy>=1.8.2 in c:\python34\lib\site-packages (from scipy)

See image. When I try to import scipy in ipython I get this '_ccallback_c' error. enter image description here

I've searched google and this site for importing scipy and this error, but nothing has shown up. Thanks for your help.

Hmm. Beeing on windows, using the official python-distribution and then calling pip install scipy will never (except you got a crazily complete system; i highly doubt that: BLAS, LAPACK, Fortran-compiler and co.) work! So double-check what happened when installing scipy. Look also here on SO for windows install scipy questions which will recommend Gohlke's binaries OR the anaconda-distribution (which i recommend). It's also the official recommendation of scipy-devs (on windows)! - sascha
Personally, and being a Windows user exclusively myself, I've learned the best way to install or upgrade packages is from binaries provided by lfd.uci.edu/~gohlke/pythonlibs . I think I recall pip install numpy didn't install the Numpy+MKL version which is needed. @sascha is right. - Jarad
SOLVED: Thanks for your help @sascha and Jarad. I installed all my packages from Gohlke and we're off and running. - Matthew

As written in the comments, Windows users like myself need to use packages from http://www.lfd.uci.edu/~gohlke/pythonlibs/ (or something alike). I downloaded the packages I wanted of the correct type (python 3.4, 64 bit windows) and extracted them in my Python>Lib>site-packages folder. Time for data analysis.
