import scipy.sparse failed

My python is 3.5.1 (32-bit) at Win7 (32-bit). I've installed 'scipy-0.16.1-cp35-none-win32.whl' and 'numpy-1.10.2+mkl-cp35-none-win32.whl' downloaded form http://www.lfd.uci.edu/~gohlke/pythonlibs/. And the scipy model can be imported correctly as below:

import scipy

But I get the errors when importing scipy.sparse:

>>> import scipy.sparse Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32\lib\site-packages\scipy\sparse\__init__.py", line 213, in <module> from .csr import * File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32\lib\site-packages\scipy\sparse\csr.py", line 13, in <module> from ._sparsetools import csr_tocsc, csr_tobsr, csr_count_blocks, \ ImportError: DLL load failed: The specified module could not be found.

And I got the error below by installing scipy by pip:

pip install scipy

Command "c:\users\administrator\appdata\local\programs\python\python35-32\python.exe -c \ """import setuptools, tokenize; __file__='C:\\Users\\ADMINI~1\\AppData\\Local\\Temp\\pip-build-qzcp2rwj\\scipy\\s‌​etup.py'; exec(compile(getattr(tokenize, 'open', open)(file).read().replace('\r\n', '\n'), file, 'exec'))""" \ install --record C:\Users\ADMINI~1\AppData\Local\Temp\pip-lyz7f9x_-record\install-record.txt \ --single-version-externally-managed --compile" failed with error code 1 in C:\Users\ADMINI~1\AppData\Local\Temp\pip-build-qzcp2rwj\scipy

How can I correctly import scipy.sparse?

Answer1:

Fixed this issue by installing python 3.4 and 3.4 dependencies from http://www.lfd.uci.edu/~gohlke/pythonlibs/. It seems the error only reproduced by python 3.5 environment.

The correct environment configurations are:

    <li>OS: Win7 (32-bit)</li> <li>Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:43:06) [MSC v.1600 32 bit (Intel)] on win32</li> <li>scipy-0.17.0rc1-cp34-none-win32.whl</li> <li>numpy-1.10.2+mkl-cp34-none-win32.whl</li> </ul>
