Sklearn __init__.py error

Question

I am receiving an error when trying to install Sklearn via pip from a .whl file.

I have read all of the existing comments about uninstalling Sklearn and going to http://www.lfd.uci.edu/~gohlke/pythonlibs/ to download the file after installing Numpy & Scipy.

For whatever reason, I keeping getting the following error:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import sklearn
  File "C:\Users\username\AppData\Local\Programs\Python\Python35\lib\site-packages\sklearn\__init__.py", line 57, in <module>
    from .base import clone
  File "C:\Users\username\AppData\Local\Programs\Python\Python35\lib\site-packages\sklearn\base.py", line 9, in <module>
    from scipy import sparse

    from ._sparsetools import csr_tocsc, csr_tobsr, csr_count_blocks, \
ImportError: DLL load failed: The specified module could not be found.

I have windows 7 with Python 3.5 64-bit installed. I can import Numpy & Scipy without issue just Sklearn will not work.

I have tried to run the setup.py file as well but that has not fixed the issue.

Answer 1

I had the same error when trying to import scikit-learn inside a python script.

My config: Python v3.4 ; Platform = Windows 10.

Here what I've done to resolve the issue:

• I uninstall numpy, scipy and scikit-learn via pip.
• I install numpy+mkl with the wheel "numpy‑1.12.0+mkl‑cp34‑cp34m‑win_amd64.whl" via pip
• I reinstall scipy with the wheel "scipy‑0.19.0rc2‑cp34‑cp34m‑win_amd64.whl" via pip
• I reinstall scikit-learn via pip

Notes:

• I downloaded the wheels on the link you give: http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
• I opened my terminal (Git Bash) as an administrator

Here is the list of all the libs I have:

As an alternative to Ant0nin's solution, I suggest you to install Anaconda package:
