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!
