Error importing sklearn

[Erick Fonseca]

I tried to import sklearn and got the following error:

In [1]: import sklearn
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line string', (1, 2))

It seems that scikit-learn has not been built correctly.


If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.


If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

I'm running Windows 8 with Python (x, y) 2.7.6.1. It is weird because I could use sklearn previously (actually, I got this error trying to run a script I had written and tested on this computer).

I checked that sklearn has a module named __check_build whose __init__.py file has the following line:

from ._check_build import check_build

And indeed there is no _check_build in my installation.

Any help is appreciated.
