I get the following error on my Ubuntu 10.10 box for the SparseSolve.py
example from the wiki:
angus@bleeder:~/src/python/pycuda-0.94.2/examples/wiki-examples$ python

SparseSolve.py:28: RuntimeWarning: divide by zero encountered in true_divide

I found this error in the archives a couple months back and the
recommendation was to install Cython. However, I have Cython installed and
I still get the error. I'm running the 4.0.17 version of the CUDA toolkit.
Several other PyCUDA examples work fine, as do the cuda examples that come
with the SDK.
On a related note, I'm assuming the sparse-solver only works with symmetric
positive-definite matrices (as it's labeled a cg solver). Do you know of
any PyCUDA development that will solve general sparse matrices?
