hello how can I convert pkl file to mesh.obj file ?

Hi, I am trying to convert pickle object to RDS object, is there a way to convert json to RDS further, to give context, we are building GBM model in python so model object is getting saved as pickle, but due to legacy reasons we have to do deployment in R, looking for a way around here.
