python - Error when calling scikit-learn using AMD64 build of Scipy on Windows -


i getting error on line:

from sklearn.ensemble import randomforestclassifier

the error log is:

traceback (most recent call last):   file "c:\workspace\kaggledigits\kaggledigits.py", line 5, in <module>     sklearn.ensemble import randomforestclassifier   file "c:\python27\lib\site-packages\sklearn\ensemble\__init__.py", line 7, in <module>     .forest import randomforestclassifier   file "c:\python27\lib\site-packages\sklearn\ensemble\forest.py", line 47, in <module>     ..feature_selection.selector_mixin import selectormixin   file "c:\python27\lib\site-packages\sklearn\feature_selection\__init__.py", line 7, in <module>     .univariate_selection import chi2   file "c:\python27\lib\site-packages\sklearn\feature_selection\univariate_selection.py", line 13, in <module>     scipy import stats   file "c:\python27\lib\site-packages\scipy\stats\__init__.py", line 320, in <module>     .stats import *   file "c:\python27\lib\site-packages\scipy\stats\stats.py", line 241, in <module>     import scipy.special special   file "c:\python27\lib\site-packages\scipy\special\__init__.py", line 529, in <module>     ._ufuncs import * importerror: dll load failed: specified module not found.

after installing:

  • python 2.7.4 windows x86-64
  • scipy-0.12.0.win-amd64-py2.7.‌exe (from here)
  • numpy-unoptimized-1.7.1.win-amd64-py2.7.‌exe (from here)
  • scikit-learn-0.13.1.win-amd64-py2.7.‌exe (from here)

anybody know why happening , how solve ?

as christoph gohlke mentioned on download page, scikit-learn downloadable website requires numpy-mkl. therefore made mistake using numpy-unoptimized.

the link numpy-mkl statically linked intel's mkl , therefore not need additional download (no need download intel's mkl).
