值错误：numpy.dtype的大小不正确，具有导入分解

Question

我试图使用sclearn.decomposition，但出现以下错误：

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

  File "numpy.pxd", line 155, in init sklearn.utils.murmurhash (sklearn/utils/murmurhash.c:5029)
ValueError: numpy.dtype has the wrong size, try recompiling

我试着用pip卸载和安装所有的包。不知道还有什么可以尝试的建议？

更新：

结果发现我安装了一个旧版本的numpy/scipy，我手动删除了它们，但现在我得到了以下运行时错误：

似乎二进制文件有问题。我在pandas上也遇到了同样的错误，我通过卸载numpy和pandas并重新安装修复了这个错误。

pip uninstall numpy
pip uninstall pandas
pip install pandas==0.13.1

注意，安装pandas也会安装它的依赖项，比如numpy。

看起来你对纽比和希比的版本也很老了。尝试更新它们。
