Hi ! all,

I just installed scikit-learn and followed with
http://scikit-learn.org/stable/tutorial/basic/tutorial.html

Then I faced a problem when I tried to load dataset from sklearn.

------------------------------------------------------------------------------------------------

Python 2.7.5 (default, Mar 9 2014, 22:15:05)

[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

from sklearn import datasets

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "/Library/Python/2.7/site-packages/sklearn/datasets/__init__.py",
line 7, in <module>

from .base import load_diabetes

File "/Library/Python/2.7/site-packages/sklearn/datasets/base.py", line
25, in <module>

from ..utils import check_random_state

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

------------------------------------------------------------------------------------------------

I've tried reinstall scipy, numpy and scikit-learn, but it doesn't help.

Can anyone give me some advise?

Thank a lot!

Are you sure you are 32/64 bit libraries uniformly?

I have no idea about recompiling.
But I found the solution.
I remove scikit-learn installed by pip and install with
https://github.com/scikit-learn/scikit-learn.
And the problem was resolved.

Thanks everybody!
