Hello, I'm trying to run the cg example posted at https://andreask.cs.illinois.edu/PyCuda/Examples/SparseSolve
where I have copied the file into one called: py_cuda_cg_test.py I'm testing using a 5 by 5 sparse symmetric .mm file I found here https://people.sc.fsu.edu/~jburkardt/data/mm/m_05_05_crs.mm though after some messing around I don't think that the file matters much when I run the command $ python py_cuda_cg_test.py m_05_05_crs.mm --is-symmetric I get the error: Traceback (most recent call last): File "py_cuda_cg_test.py", line 88, in <module> main_cg() File "py_cuda_cg_test.py", line 35, in main_cg spmv = PacketedSpMV(csr_mat, options.is_symmetric, csr_mat.dtype) File "/home/bs162/.local/lib/python2.7/site-packages/pycuda/sparse/packeted.py", line 185, in __init__ local_row_costs) File "pycuda/sparse/pkt_build_cython.pyx", line 22, in pycuda.sparse.pkt_build_cython.build_pkt_data_structure (/home/bs162/.pyxbld/temp.linux-x86_64-2.7/pyrex/pycuda/sparse/pkt_build_cython.c:1219) TypeError: 'numpy.float64' object cannot be interpreted as an index which seems to indicate that the index information is somehow being cast from an int to a float during the call to packeted.py I get this error with both python 2.7 and 3.6 and I am using numpy 1.13.3. Any help would be greatly appreciated! Thank you! _______________________________________________ PyCUDA mailing list -- pycuda@tiker.net To unsubscribe send an email to pycuda-le...@tiker.net
