Python Sklearn在eclipse IDE中不再工作

Question

我更新了Sklearn包：

sudo pip install -U numpy scipy scikit-learn

在macosx 10.8（山狮）中，一切都很好。我通过终端（命令行）对它进行了测试，它工作正常。但是这个包在我的IDE eclipse（juno）中停止了工作。我得到错误：

  File "numpy.pxd", line 155, in init scipy.special._ufuncs (scipy/special/_ufuncs.c:21818)

有什么帮助吗？

我使用PyDev，所以我向您报告与此插件相关的"良好实践"。强烈建议您每次更新python包时都更新"python解释器"PYTHONPATH。要执行此操作，请转到：

Windows->首选项->PyDev->解释器->Python解释器

在该位置，您可以使用"快速自动配置"按钮或手动查看并更正PYTHONPATH。
