I am new to Python and I am trying to install numpy+mkl and scipy (in the same order), but I get below error when I execute following steps:

import pandas as pd  
import numpy as np  
from sklearn.preprocessing import LabelEncoder

I am using Python 3.5 (32-bit) on a Windows 7 64-bit OS.

There is a similar question already answered for the exact problem here: ImportError: cannot import name NUMPY_MKL

Going through the answer, I reinstalled my numpy+mkl pkg numpy‑1.11.2+mkl‑cp35‑cp35m‑win32.whl from the mentioned link (http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy) and then reinstalled scipy-0.18.1-cp35-cp35m-win32.whl as well, but that does not solve the problem and I still get the same error:

>>> exec(open("C:\\PythonFiles\\testpy1.py").read())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 3, in <module>
  File "C:\Users\msoudagar\AppData\Local\Programs\Python\Python3532\lib\site-packages\sklearn\__init__.py", line 57, in <module>
    from .base import clone
  File "C:\Users\msoudagar\AppData\Local\Programs\Python\Python35-32\lib\site-packages\sklearn\base.py", line 10, in <module>
    from scipy import sparse
  File "C:\Users\msoudagar\AppData\Local\Programs\Python\Python3532\lib\site-packages\scipy\__init__.py", line 61, in <module>
    from numpy._distributor_init import NUMPY_MKL  # requires numpy+mkl
ImportError: cannot import name 'NUMPY_MKL'

Any inputs would be really helpful!

  • In the error message there's a path with `Python3532` and another with `Python35-32`. That seems fishy. Also, since you're reinstalling, why not use 64-bit python? – user7138814 Nov 20 '16 at 17:28

Try commenting out the line from numpy._distributor_init import NUMPY_MKL it might just work regardless.

ImportError: cannot import name NUMPY_MKL

I know this is not the most sophisticated of solutions but, all I had to do was close the IDE(in my case, Pycharm) and re-open it again.

Not sophisticated but effective in my case :).

Suggesting to download ready made binary setup from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

pip install xx.whl

I ran into the same issue on Windows with Python 3.5 64 bit. Manually installing numpy+mkl from wheel file solved the issue for me. Select the appropriate wheel file from here (cp35,win32 for you): and install it using pip install --user Path_to_local_file.whl replacing Path_to_local_file with wherever you saved the .whl file

This is a also a duplicate of ImportError: cannot import name NUMPY_MKL
