Bug Description

In the Python interpreter, we get the following trace by importing the rpy module:

>>> import rpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/rpy.py", line 134, in <module>
    """ % RVERSION)
RuntimeError: No module named _rpy2111

      RPy module can not be imported. Please check if your rpy
      installation supports R 2.11.1. If you have multiple R versions
      installed, you may need to set RHOME before importing rpy. For

      >>> from rpy_options import set_options
      >>> set_options(RHOME='c:/progra~1/r/rw2011/')
      >>> from rpy import *

Indeed, the rpy package is built for R 2.11.0, and not R 2.11.1 that is shipped with Ubuntu Maverick.

$ dpkg -L python-rpy | grep -e "_rpy.*\.so"

A fix has been released in Debian few months ago, in source version 1.0.3-15.

MikeM is also experiencing this bug (cf. question 131480), so I marked it as confirmed.

To fix this bug, package python-rpy 1.0.3-15 should be synced from Debian.

python-rpy 1.0.3-15 is currently available in Debian Squeeze: http://packages.debian.org/squeeze/python-rpy

I am working with python and rpy. I would like to know whether there is a way of installing python-rpy 1.0.3-15.


Jérémy Subtil (bigmadwolf) wrote :


I uploaded in my PPA the python-rpy 1.0.3-15 Debian package: ppa:bigmadwolf/misc

A friend of mine tried this package and reported it was working fine.

Note that this is only a workaround, a so easy bug to fix thanks to a Debian sync *MUST* be fixed in Ubuntu Maverick, it shouldn't be needed to wait for Ubuntu Natty.

Installing the debian package as sugested by Jérémy Subtil works for me. Precisely:
1. I downloaded the debian python-rpy package from the page given by Jérémy Subtil
2. I uninstalled the ubuntu python-rpy package
3. I installed the downloaded debian package (dpkg -i filename.deb)

Thanks for this solution.

Thanks to Jérémy for the PPA. Why hasn't this been fixed in Maverick, though?

Bug still present in Oneiric, but the fix by Jérémy Subtil does not seem to work anymore (python 2.6 required).

Hi, Im really new to this forum and in general to Ubuntu and Im a girl ;-)
Ive just upgraded to Ubuntu 11.10 (Gnome) and I also encountered this problem.

I checked in synaptic package manager and rpy was installed but didn't want to be imported to python
spitting out the same statements as above. I just manged to fix it.
What I did, Ive followed advice from amaneiro (amaneiro) on 2008-02-07:


I have R 2.13.0 (my own installation from source) and Python 2.7.2+, which came with oneric.

This bug was fixed in Natty but has reoccurred in oneric :-(

Good luck!
