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。在集群中的库下我可以安装它们，它甚至说 "Installed"，但是当我尝试导入它们时它会出错，就好像它没有正确安装一样。在本地系统中完美运行。

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。无非是pymer4包的依赖包版本问题。将以下软件包的版本更改为 pymer4 发布日期之前的最新版本并且有效：

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