Question

我正在尝试在交互式python环境中导入sklearn模块，但是我收到此错误消息：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  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

我在某处读到这可能是一个问题，因为scikit-learn是针对较旧版本的numpy编译的，但我试图卸载并重新安装numpy和scikit-learn（和scipy以确定）和问题依然存在。

这些是我的python模块：

Answer 1

我明白了。我安装了多个版本的python（2.3,2.5,2.6,2.7）和Numpy的多个版本。交互式shell中使用的那个是numpy 1.6。我把它们全部删除了，并用numpy安装了新的，现在它可以工作了。

导入sklearn失败 - 与numpy版本冲突？
