Error when trying to import sklearn modules : ImportError: DLL load failed: The specified module could not be found

问题

I tried to do the following importations for a machine learning project:

from sklearn import preprocessing, cross_validation, svm
from sklearn.linear_model import LinearRegression

I got this error message:

Traceback (most recent call last):

Please help I tried everything but nothing worked. I tried these solutions as well: ImportError: DLL load failed: Le module spécifié est introuvable

ImportError: DLL load failed: The specified module could not be found

回答1:

You should open up "C:\Python27\lib\site-packages\sklearn\utils\fixes.py", and edit the contents. There are two specific changes you should make:

First, copy-and-paste the contents of https://github.com/scikit-learn/scikit-learn/blob/74a9756fa784d1f22873ad23c8b4948c6e290108/sklearn/utils/fixes.py into the file "C:\Python27\lib\site-packages\sklearn\utils\fixes.py".

Second, replace the line if np_version < (1, 12, 0): with if np_version < (1, 12):.

More background info and detail available here, in a great answer from user DSM.

回答2:

This line points to scipy.

from scipy.sparse.linalg import lsqr as sparse_lsqr

You can try:

pip uninstall scipy

pip install scipy

enjoy!

回答3:

Install this numpy library instead of the one you use:

http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

I assume you have Intel Math Kernal Libary installed.
