I'm fairly certain that Python defaults to 64 bit on Snow Leopard (but I run Leopard so can't confirm): http://wiki.tiker.net/PyCuda/Installation/Mac#Notes_about_Snow_Leopard
Someone else had a similar error in the past: http://host304.hostmonster.com/pipermail/pycuda_tiker.net/2010-January/000884.html It might be worth downgrading to CUDA 2.3 - I think people in the past have had pyCUDA working (you'll want to go back through the threads to be sure). CUDA 3.0 is very new, maybe there are bugs that still need fixing? See here for another user with 32/64bit Snow Leopard issues: http://host304.hostmonster.com/pipermail/pycuda_tiker.net/2010-March/thread.html#1059 Here a user gets pyCUDA 0.93 working on Snow Leopard - there's something about changing the default build to 32bit (in 0.93) which you might need to change when building on 64 bit (but that's a guess!): http://host304.hostmonster.com/pipermail/pycuda_tiker.net/2010-January/000916.html >From my own knowledge getting pyCUDA 0.94rc works fine on Leopard (32 bit) with CUDA 2.3. i.
