rpy2.ipython与pandas/numpy的错误

试图使用ipython的

rpy2.ipython

（以前的“rmagic”）扩展来获得交互式R（

%R

行魔法和

%R

单元格魔法函数），我得到以下错误

AttributeError: module 'numpy' has no attribute 'core'

没有错误，所以我不确定是否确实存在未构建的文件，可能只是一个变量被另一个变量屏蔽了（例如，

rpy2

中的错误）

import numpy.core

（等），无需先尝试加载

rpy2.ipython

即可正常工作

我怀疑LAPACK库的版本之间存在不兼容：在您的系统上运行时选择的版本、构建numpy时使用的版本和构建R时使用的版本

在虚拟环境中从源代码安装numpy、R和rpy2应该可以解决这个问题。另一种方法是通知相关的anaconda软件包的维护人员，并确保他们确认anaconda打包的numpy和R使用相同的LAPACK
