ImportError: cannot import name NUMPY_MKL

I am trying to run the following simple code
import scipy
scipy.test()
But I am getting the following error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 586, in runfile

File "C:\Python27\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
I am using python 2.7 under windows 10.
I have installed scipy but that does not seem to solve the problem
Any help is appreciated.

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.

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'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

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 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 <destination of your .whl file>

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.

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.

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).

yes,Just reinstall numpy,it works.

How do I install Matplotlib as a Macintosh Yosemite User

I am a Macintosh Yosemite user. When I try to import matplotlib I get the following error.
import matplotlib

When I use from pylab import axis that would work just fine. I do not know what is going on and I am just so lost. I have tried using homebrew, macports installs, dmg installs. I also have very little experience installing things through terminal so I just followed what other people said. Though, that is still not working.

Mac OS X ships with python by default. And there is one provided by homebrew. I would recommend using homebrew python over the default python.
Here, I suspect your numpy installation has landed up in the site-packages directory managed by the non-homebrew pip package manager whereas matplotlib package is installed in a different site-packages directory. (But I am not sure). Nevertheless it has something to do with multiple python's / package managers being used. This may not be the best answer, but so far the only solution I can think of to fix your problems is to uninstall pip and also remove everything in any python site-packages directory you can find on your filesystem,. And install python via homebrew again, and then install all packages required using the pip (which gets installed automatically when you install python using homebrew)
Warning: Make sure you list out the package names and store the names somewhere before deleting them because you will have to install them again.
brew uninstall python
#(ATTN) Uninstall macports and don't use it with brew
#(ATTN) Delete the contents of all python site-packages directories
rm /usr/local/lib/python2.7/site-packages/*
brew install python
# Homebrew comes with its own pip installed
pip install <package1>, <package2> ...
Here is a related question from someone who faced a similar problem:
Numpy build fails with cannot import multiarray
My advice: Don't use Homebrew and Macports or any other package manager together. They mess up with each other and I have faced the consequences in the past.I just use homebrew python now. For installing scientific python packages either Anaconda or Canopy (choose one) are really helpful, which can be installed on top of the homebrew python.

After having a lot of problems similar to the ones you describe, using sudo pip install -U matplotlib worked fine for me.

Python cannot import pylab [duplicate]

At some point in the last few days, Matplotlib stopped working for me on OS X. Here's the error I get when trying to import matplotlib:
Traceback (most recent call last):

The only system change I can think of was the Apple-forced NTP update and maybe some permission changes I did in /usr/local to get Brew working again.
I tried reinstalling both Matplotlib and Python-dateutil via Pip, but this did not help. Also tried a reboot. I'm running Python 2.7.6, which is located in /usr/bin/python. I'm running Yosemite (OS X 10.10.1).

sudo pip uninstall python-dateutil
sudo pip install python-dateutil==2.2
I had the same error message this afternoon as well, although I did recently upgrade to Yosemite. I'm not totally sure I understand why reverting dateutil to a previous version works for me, but since running the above I'm having no trouble (I generally use pyplot inline in an ipython notebook).

This problem is fixed in the latest six and dateutil versions. However, in OS X, even if you update your six to the latest version, you might not actually update it correctly. This is what happened to me:
After doing a pip2 install six -U, the new six module was installed in /Library/Python/2.7/site-packages/. However, when I loaded six in a python 2.7 terminal, and checked its path, this is what I got:
import six
print six.__file__
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.pyc
So, python was using an old version of six, which I removed by typing:
rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/six.*
This fixed this issue for me.

Installing the python-dateutil==2.2 did not work for me.
But a quick-and-dirty workaround did work! I replace six.py in python 2.7 with the six.py from python 3.4 (virtualenv). Since, I have the problem in 2.7 but not 3.4.
UPDATE
I had the same problem again after reinstalling python (and after upgrading to El Capitan). Un-obvious thing is that this error occurs only in the IPython shell and notebook (when I do import matplotlib.pyplot as plt) but works fine from a Python shell.
So a better solution (that did work in my case) without a dirty work-around is to force install both six and ipython. Here is what I did to have this fixed :
$ pip install --ignore-installed six
$ pip install --ignore-installed ipython

It is possible that you have a perfectly installed version of any packages you have installed, but the version used by default is not the one you want. You can see the list of paths that python search from in order to find its packages as follows:
>>> import sys
>>> sys.path
In order to let python search first the most updated version of certain package, instead of removing the system version, what can be done is to set the system variable PYTHONPATH in the ~/.bash_profile (or ~/.bashrc if linux) config file to the path where the new packages are installed:
export PYTHONPATH=/Library/Python/2.7/site-packages
An alternative is to modify the python path inside your python script by adding the path at the beginning of the path list:
import sys
sys.path.insert(1,'/Library/Python/2.7/site-packages')
This needs to be done for every script you need a certain package version. You might want for some reason use an older version that you have installed.
BTW all my installations with easy_install, or pip, or from sources go to /Library/Python/2.7/site-packages
This worked en EL Capitan, and now also in macOS Sierra (10.12.2)

ImportError: matplotlib requires dateutil; import matplotlib.pyplot as plt

Am new to progamming and Python, i keep getting the error below when i run my program. Someone advised i should use pip to solve it. But cant pip get installed using the cmd. Though i suceeded using Powershell but still cant make it work. How do i solve this, any tips will go along way. Thanks

Am using version 2.7.3

You need to install various packages to get numpy working correctly.
libsvm-3.17.win32-py2.7
pyparsing-2.0.1.win32-py2.7
python-dateutil-2.2.win32-py2.7
pytz-2013.9.win32-py2.7
six-1.5.2.win32-py2.7
scipy-0.13.3.win32-py2.7
numpy-MKL-1.8.0.win32-py2.7
Matplotlib
Download all the binaries from this link and install and then you will have a working numpy installation.

You're probably looking for:
pip install python-dateutil

The error states that you are missing Dateutil.
This could mean that you did not install Dateutil with pip install python-dateutil or your way to install Python modules. But if you did your pip install and still get the same error it could also mean that DateUtil is installed in a folder where your Python distribution does not expect it.
In my case (Mac OSX) I installed pip with Brew http://brew.sh/. That pip will install the modules in: /usr/local/lib/python2.7/site-packages/
However the standard Mac OSX Python distribution will look for modules in /Library/Python/2.7/site-packages/
Your folders could be different of course, but you can check where Python looks for modules with:
import sys
print sys.path
Check this and see if one of the directories in the list contains the directory where dateutil is installed.
If not add a PYTHONPATH environment variable: Like: PYTHONPATH=/usr/local/lib/python2.7/site-packages/ or the folder where your dateutil is installed

I did pip install python-dateutil, but kept getting the same error. I got past that error by installing from http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-dateutil
Look for the Matplotlib section and install the dependencies you don't have.
Matplotlib is a 2D plotting library.
Requires numpy, dateutil, pytz, pyparsing, six, setuptools, and optionally pillow, pycairo, tornado, wxpython, pyside, pyqt4, ghostscript, miktex, ffmpeg, mencoder, avconv, or imagemagick.

scikits.audiolab doen't import into python (numpy.dtype)

ValueError: numpy.dtype does not appear to be the correct type object
How do I fix this?
Any alternative package that can do the job?

I had the same issue and for me it was caused by installing another (more recent) version of NumPy.
Check if you have different versions of NumPy installed and try switching back to an older one. For my part: I had a system-wide installation of Python and common modules like NumPy, which I couldn't touch because I'm not admin on that system. So when I installed some other library locally (in ~/.local/lib/python2.7/) it would also install more recent versions of SciPy and NumPy and put them into that local folder. And when importing the module it would draw from the local directory first before looking at the system-wide libraries which were working fine before with scikits.audiolab. So for me it was solved by
pip uninstall numy && pip uninstall scipy because that only deleted the newer local versions of numpy.
But more specific to your case, here is a tutorial how (on a Mac) to switch to a certain version of NumPy:
multiple numpy version on Mac OS X
The NumPy version I found working for my scikits.audiolab is 1.6.1
>>> import numpy
>>> numpy.version.version
'1.6.1'
Hope that helps. :)

Maybe you installed/upgraded numpy after installing talkbox. Try running this command:
pip install --upgrade --force-reinstall scikits.talkbox
