Same problem on WinPython-64bit-3.3.5.0
Trying to call sklearn which needs to import sparse from scipy
I think the _imp module is lacking, no ?

What I report is on a 64-bit machine, I tried sklearn on a 32-bit machine with 
WinPython-32bit-3.3.5.0 and it works.
I don't find neither _imp, so what I say above about the lack of _imp must be 
wrong (I don't really know where and what should be _imp)

I do not see the problem when I use WinPython-64bit-3.3.5.0.  Do you have the 
file 
`WinPython-64bit-3.3.5.0\python-3.3.5.amd64\Lib\site-packages\scipy\sparse\spars
etools\_csr.pyd`?
