If you got this error: ValueError: numpy.dtype does not appear to be the correct type object, try to installing Numpy 1.3. After you install Divisi (ex. on Windows), copy the content under C:\Python25\Lib\site-packages\conceptnet-4.0rc2-py2.5.egg to C:\Python25\Lib\site-packages\csc. Otherwise, you might get error message like “module csc does not exist.”
