Anacondas 安装与 IPython 熊猫导入混淆？

Question

我正在使用 IPython 和 pandas 进行一些数字运算，最近安装了 Anaconda 来尝试一下。我没有设置 virtualenv（我现在学到了为什么它如此有价值的教训）并且它一定已经调整了一些东西，现在我在将 pandas 导入我的脚本时遇到错误。到目前为止，我已经发现 pandas 导入对英特尔库 libmkl_intel_lp64.dylib 造成了一些麻烦，但除此之外没有太多。

抱歉，有人可以就如何解决问题提供一些见解吗？谢谢！

Answer 1

如果您查看回溯，您可以看到它正在从 Canopy 加载内容，即使您是从 Anaconda 开始的。这通常意味着您设置了PYTHONPATH。你应该取消它。

Answer 2

检查环境变量PATH，它应该包含安装 Anaconda 的目录的一些路径，您必须将其删除以避免调用 Anaconda 的 Python。

然后检查PYTHONPATH，它告诉 Python 模块应该从哪里导入，如果有任何 Anaconda 包的路径，您也可以将其删除。

最后，正如您已经意识到的那样……强烈推荐virtualenv。
