如何在Databricks中安装python包'rpy2'？

Question

我正在尝试在Databricks中安装和使用pymer4包功能，这也需要安装rpy2。在群集中的库下我可以安装它们，它甚至会显示“已安装”，但是当我尝试导入它们时，它会出错，就像它没有正确安装一样。在本地系统中它完美运行。

from pymer4.test_install import test_install

错误是：

ImportError: No module named 'pandas.core.dtypes'

Answer 1

能够解决我自己的问题。这只是pymer4包的依赖包的版本问题。使用pymer4发布日期之前的最新版本更改了以下软件包的版本并且它有效：

matplotlib==3.0.2
pandas==0.23.4
rpy2==2.9.4
