I try to use sparse matrix operations in GPU in Python and now try to use PyCUDA with theano. But I can't find how to do sparse matrix and vector multiplication. I only got an example showing how to solve $A\cdot x=b$ using CG from the library document. Is there any document or example detailing how to do some basic sparse matrix operations?
By the way, is there another python library that can do sparse matrix operations in GPU?
