I\'m using Rpy2 on windows 7 64 and having trouble loading a package:
using(mi)
from rpy2.robjects
In python: Check the version of R being used by rpy2
import rpy2.robjects as robjects
robjects.r['version']
Check your rpy2 library location
base = importr('base')
print(base._libPaths())
In R: Check your R library location for this version of r
.libPaths()
copy the library installed in your version of r to the folder used by rpy2.
