机器学习代码中的numpy.dtype错误（Python）

Question

I am just trying to run a scikit-learn example source code successfully, but am getting an consistent error. The code can be found here - it has around 90 lines of code, so it wouldn't be efficient to put it in here. However, whenever I run it, I get the error message called from the Import sklearn stating:

File "plot_outlier_detection.py", line 33, in <module>
  from sklearn import svm
File "/Library/Python/2.7/site-packages/sklearn/__init__.py", line 57, in <module>
  from .base import clone
File "/Library/Python/2.7/site-packages/sklearn/base.py", line 11, in <module>
  from .utils.fixes import signature
File "/Library/Python/2.7/site-packages/sklearn/utils/__init__.py", line 10, in <module>
  from .murmurhash import murmurhash3_32
File "numpy.pxd", line 155, in init sklearn.utils.murmurhash (sklearn/utils/murmurhash.c:5029)
ValueError: numpy.dtype has the wrong size, try recompiling

The main error is

ValueError: numpy.dtype has the wrong size, try recompiling

and I've looked into many Stackoverflow posts already, saying that I need to update my numpy, matplotlib, scipy, which I've done already multiple times (upgrade / uninstall+install using pip / uninstall+install from source), but the same error still shows up (I also reinstalled sklearn). I think I know why this is the case:

When I use python in terminal and check the numpy version I get

import numpy
numpy.version.version
'1.9.2'

However, when I try installing or upgrading through pip -- I get the message

numpy in /Library/Python/2.7/site-packages/numpy-1.11.0-py2.7-macosx-10.10-intel.egg

I read in this Stackoverflow query about this, and they said to use easy_install as python doesn't read from the right path in Macs (IDK, can someone confirm?) so I did it through easy_install, and get this message

Searching for numpy

numpy 1.11.0 is already the active version in easy-install.pth
Installing f2py script to /usr/local/bin

Using /Library/Python/2.7/site-packages/numpy-1.11.0-py2.7-macosx-10.10-intel.egg
Processing dependencies for numpy
Finished processing dependencies for numpy

which is the exact same thing. I don't really know what's going on. Can anyone help me?

For reference of versions:

Python - 2.7.10
Numpy - 1.9.2
Matplotlib - 1.4.3
Scipy - 0.13.0b1

The rest of the versions are also not up to date..but they derive from numpy's version being up-to-date.

I've installed Anaconda (2.5.0) on my Ubuntu (14.04) With Anaconda 2.5.0 my versions are:

python 2.7.11

Numpy 1.10.4

Scipy 0.17.0

I've download the code from the link, and it worked perfectly on my machine

Can you try to install Anaconda and see if it solve your problems? https://www.continuum.io/downloads
