I am getting the following error while trying to import from sklearn:

>>> from sklearn import svm

Traceback (most recent call last):
  File "<pyshell#17>", line 1, in <module>
   from sklearn import svm
  File "C:Python27libsite-packagessklearn__init__.py", line 16, in <module>
   from . import check_build
ImportError: cannot import name check_build

I am using python 2.7, scipy-0.12.0b1 superpack, numpy-1.6.0 superpack, scikit-learn-0.11 I have a windows 7 machine

I have checked several answers for this issue but none of them gives a way out of this error.
