I am currently using Python(2.7.8), sklearn(0.15.2), pandas(0.15.1), multiprocessing, and rpy2(2.5.1) at the same time. My OS is Mac OS X 10.10.
I am trying to run multiple processes run GridSearchCV training on the same dataset with different parameters. Before writing code for rpy2, I checked that it works as expected. However, if I include import code for rpy2 (without writing any actual code for them) my program quits unexpectedly in the middle GridSearchCV fit method.
I imported the following, and importing any one of them causes this problem.
from rpy2.robjects.packages import importr
import rpy2.robjects as ro
import pandas.rpy.common as com
