I'm running into errors importing a library in python. Here are the details.
I'm running Windows 7 (64 bit), python 2.7.10 (64 bit), and have installed a few 64 bit packages from http://www.lfd.uci.edu/~gohlke/pythonlibs/ Using the standard "pip install ***.whl".
Everything has been working fine for months. Today, (after a windows update), I get an error with a specific import.
>>> import sklearn # No problem here!
>>> import sklearn.cross_validation
Traceback (most recent call last):

ImportError: DLL load failed: %1 is not a valid Win32 application.
"Not a valid win32 application" leads me to believe that something in the dependencies is installed as a 32 bit library.
To tackle this, I reinstalled scipy, sklearn, numpy, and pandas (all 64 bit). Still the same error.
Then I tried reinstalling everything- completely removing python and reinstalling with all the packages. Still the same error.
Here is the output of "pip list"
