I hit this problem at the weekend. It seemed to occur only when importing rpy from a django view function. So I tried importing rpy from settings.py, so it happens once at the start of the django run. My settings.py starts like this: from rtest.rshim import myR Because for some reason I factored out the rpy import into rshim.py within an app. It looks like this: from rpy import r myR = r and then view code that needs rpy does this: from project.rtest.rshim import myR as r I'm not sure if that level of complexity is strictly necessary. I think the root cause is starting up R from a view which maybe is running in some odd thread context. Maybe this works for you too. I'm on rpy 1.x and R 2.9.x and django-latest-stable using django's built in server. I'm not sure what happens if you get multiple requests, but then django's test server (I think) blocks on each request. Running from apache with mod-python? I have no idea... I'd do some serious testing before making any kind of production system with this. Or possible move the R business onto a separate server with Rserver.
