i'm trying import sklearn, when attempt receive following:

--------------------------------------------------------------------------- importerror                               traceback (most recent call last) <ipython-input-2-8fd979e02004> in <module>() ----> 1 import sklearn  c:\users\alpine\appdata\local\enthought\canopy\user\sklearn\__init__.py in <module>()      29     # process, may not compiled yet      30 else: ---> 31     . import __check_build      32     .base import clone      33   c:\users\alpine\appdata\local\enthought\canopy\user\sklearn\__check_build\__init__.py in <module>()      44     ._check_build import check_build      45 except importerror e: ---> 46     raise_build_error(e)  c:\users\alpine\appdata\local\enthought\canopy\user\sklearn\__check_build\__init__.py in raise_build_error(e)      39 build package before using it: run `python setup.py install` or      40 `make` in source directory. ---> 41 %s""" % (e, local_dir, ''.join(dir_content).strip(), msg))      42       43 try:  importerror: no module named _check_build ___________________________________________________________________________ contents of c:\users\alpine\appdata\local\enthought\canopy\user\sklearn\__check_build: setup.py                  setup.pyc                 _check_build.c _check_build.pyx          __init__.py               __init__.pyc ___________________________________________________________________________ seems scikit-learn has not been built correctly.  if have installed scikit-learn source, please not forget build package before using it: run `python setup.py install` or `make` in source directory.  if have used installer, please check suited python version, operating system , platform.  error: unexpected error occurred while tokenizing input following traceback may corrupted or invalid error message is: ('eof in multi-line string', (1, 2))

i'm sure scikit-learn has been correctly built managed run python setup.py install without incident. did try running python setup.py bdist_wininst -b doc/logos/scikit-learn-logo.bmp though interrupted @ error: cannot copy tree 'build\scripts.win-amd64-2.7': not directory.

might have idea on how fix this?

ok, following work me :)

sudo make sudo python setup.py install

finally, test whether installation ok:

nosetests --exe sklearn

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
