Hi. Im Youngsu-park ,in POSTECH in south korea.

I had same problem on scipy importing like:

    from scipy import *

.

So I looked at the scipy/sparse folder,

"C:\Python25\Lib\site-packages\scipy\sparse".

To find the reason of error, I open the

"C:\Python25\Lib\site-packages\scipy\sparse\sparse.py", file.

>From line 21 to 26, there was import statement for "sparsetools"



from scipy.sparse.sparsetools import cscmux, csrmux, \

     cootocsr, csrtocoo, cootocsc, csctocoo, csctocsr, csrtocsc, \

     densetocsr, csrtodense, \

     csrmucsr, cscmucsc, \

     csr_plus_csr, csc_plus_csc, csr_minus_csr, csc_minus_csc, \

     csr_elmul_csr, csc_elmul_csc, csr_eldiv_csr, csc_eldiv_csc



I change the working directory to
"C:\Python25\Lib\site-packages\scipy\sparse",

import sparestools and use dir function to see the members of sparsetools



In [16]: import sparsetoo



In [17]: dir(sparsetools)

Out[17]:

['__doc__',  '__file__',  '__name__', '__version__', 'ccootocsc', 'ccscadd',
'ccscextract',

'ccscgetel', 'ccscmucsc', 'ccscmucsr', 'ccscmul', 'ccscmux', 'ccscsetel',
'ccsctocoo',

 'ccsctofull', 'ccsrmucsc', 'ccsrmux', 'cdiatocsc', 'cfulltocsc', 'ctransp',
'dcootocsc',

 'dcscadd', 'dcscextract', 'dcscgetel', 'dcscmucsc', 'dcscmucsr', 'dcscmul',
'dcscmux',

 'dcscsetel', 'dcsctocoo', 'dcsctofull', 'dcsrmucsc', 'dcsrmux',
'ddiatocsc', 'dfulltocsc',

 'dtransp', 'scootocsc', 'scscadd', 'scscextract', 'scscgetel', 'scscmucsc',
'scscmucsr',

 'scscmul', 'scscmux', 'scscsetel', 'scsctocoo', 'scsctofull', 'scsrmucsc',
'scsrmux', 'sdiatocsc',

 'sfulltocsc', 'stransp', 'zcootocsc', 'zcscadd', 'zcscextract',
'zcscgetel', 'zcscmucsc', 'zcscmucsr',

 'zcscmul', 'zcscmux', 'zcscsetel', 'zcsctocoo', 'zcsctofull', 'zcsrmucsc',
'zcsrmux', 'zdiatocsc',

 'zfulltocsc', 'ztransp']



But it is not the members of sparsetools.py

I think it is the members of sparsetools.pyd.



Move sparsetools.pyd to some backup directory.

Then it will works well.



In [21]: from scipy import *
