有没有办法对通过rpy2导入的R模块进行腌制/序列化？ （蟒蛇）

Question

I am working on a package with a dependency on a particular program installed via R . I would rather simplify the installation process and not make the users create a backend for R with all of the packages. This may be completely unavoidable but I'm wondering if there is any possible way to supply the R objects in a serialized form via pickle or any serialization module in Python?

I tried pickle first and then tried dill but had no luck.

>>> import pickle
>>> from rpy2.robjects.packages import importr
>>> r_package = importr("dynamicTreeCut")
>>> r_package
rpy2.robjects.packages.Package as a <module 'dynamicTreeCut'>
>>> with open("./dynamicTreeCut.rpy2.pkl", "wb") as f:
...     pickle.dump(r_package, f)
...
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: can't pickle InstalledSTPackage objects

您需要R才能使用rpy2，并且如果您想使用R软件包，则必须将它们与R一起安装。如何对R和软件包进行打包是一个与rpy2相对独立的问题，并且详细介绍了可能超出SO答案范围的选项：泊坞窗图像（见rpy2自己的图像与Jupyterlab或jupyterlab和火花 ），专用安装程序预编译的二进制，或者deb文件包的.rpm，等...
