Python sklearn机器学习库的安装大坑 抛砖引玉 求大神！

本人机器学习小白 最近迷上了python机器学习 但小弟是做安卓开发的 有点python的基础  希望可以学习 自我提升一下有机会转行更好 啊哈哈

话说回来

万事开头难！！！

在我安装忘numpy scipy matplotlib 等一些基础库之后并且能顺利的在shell中import 说明安装成功了 

到了最后的步骤 需要安装sklearn库的时候  也提示安装成功了 在import的时候就报错了 日了狗了

============错误1  =========

>>> import sklearn 

Traceback (most recent call last):

============错误2 =========

>>> from sklearn import datasets

Traceback (most recent call last):

    from . import __check_build

在网上找了好久 各种方法都试过了 还是同样的错误 

自己弄了两天 浪费两天的时间  今天实在是 受不鸟了  向困难屈服了 不是不是mac os 的问题

果断转去下载了 anaconda ！！！！！！

希望给力！！

希望有大神看到 能给小弟已解释 先行谢过！！！！！！
