From your log its clear that numpy package is missing  As mention in the PyPI package      The SciPy library depends on NumPy  which provides convenient and fast N-dimensional array manipulation    So  try installing numpy package for python as you did with scipy

The reason for the error is you upgraded your numpy library of which there are some functionalities from scipy that are required by the current version for it to run which may not be found in scipy  Just upgrade your scipy library using python -m pip install scipy --upgrade  I was facing the same error and this solution worked on my python 3 5

yes Just reinstall numpy it works

I don t have enough reputation to comment but I want to add  that the cp number of the  whl file stands for your python version   cp35 -  Python 3 5 x   cp36 -  Python 3 6 x  cp37 -  Python 3 7 x  I think it s pretty obvious but still I wasted almost an hour because of this and maybe other people struggle with that  too   So for me worked version cp36 that I downloaded here  https   www lfd uci edu  gohlke pythonlibs  numpy since I am using Python 3 6 8   Then I uninstalled numpy   pip uninstall numpy    Then I installed numpy mkl   pip install  lt destination of your  whl file gt

Reinstall numpy-1 11 0 XXX whl  for your Python  from www lfd uci edu  gohlke pythonlibs  This file has the same name and version if compare with the variant downloaded by me earlier 29 03 2016  but its size and content differ from old variant  After re-installation error disappeared   Second option - return back to scipy 0 17 0 from 0 17 1  P S  I use Windows 64-bit version of Python 3 5 1  so can t guarantee that numpy for Python 2 7 is already corrected

I had the same problem while installing gensim on windows  Gensim is dependent on scipy and scipy on numpy  Making all three work is real pain  It took me a lot of time to make all there work on same time   Solution  If you are using windows make sure you install numpy mkl instead of just numpy  If you have already installed scipy and numpy  uninstall then using  pip uninstall scipy  and  pip uninstall numpy   Then download numpy-1 13 1 mkl-cp34-cp34m-win32 whl from http   www lfd uci edu  gohlke pythonlibs  numpy and install using pip install numpy-1 13 1 mkl-cp34-cp34m-win32 wh Note  in cp34-cp34m 34 represent the version of python you are using  so download the relevant version   Now download scipy from http   www lfd uci edu  gohlke pythonlibs  scipy  appropriate version for your python and system  and install using  pip install  scipy-0 19 1-cp34-cp34m-win32 whl   Your numpy and Scipy both should work now   These binaries by Christoph Gohlke makes it very easy to install python packages on windows  But make sure you download all the dependent packages from there

I recently got the same error when trying to load scipy in jupyter  python3 x  win10   although just having upgraded to numpy-1 13 3 mkl through pip   The solution was to simply upgrade the scipy package  from v0 19 to v1 0 0

User · Answer

If you look at the line which is causing the error  you ll see this   from numpy  distributor init import NUMPY MKL    requires numpy mkl   This line comment states the dependency as numpy mkl  numpy with Intel Math Kernel Library   This means that you ve installed the numpy by pip  but the scipy was installed by precompiled archive  which expects numpy mkl   This problem can be easy solved by installation for numpy mkl from whl file from here

I m not sure if this is a good solution but it removed the error   I commented out the line    from numpy  distributor init import NUMPY MKL    and it worked  Not sure if this will cause other features to break though
