Hi petsc4py users, I am running into the following error:

File "/Users/cls/workspace/LAMG-Python/src/lamg/amg/setup.py", line 945, in buildInternal Acc = A[c, c] File "Mat.pyx", line 185, in petsc4py.PETSc.Mat.__getitem__ (src/petsc4py.PETSc.c:71407) File "petscmat.pxi", line 862, in petsc4py.PETSc.mat_getitem (src/petsc4py.PETSc.c:22442) File "petscmat.pxi", line 773, in petsc4py.PETSc.matgetvalues (src/petsc4py.PETSc.c:21226) File "arraynpy.pxi", line 123, in petsc4py.PETSc.iarray_i (src/petsc4py.PETSc.c:5284) File "arraynpy.pxi", line 117, in petsc4py.PETSc.iarray (src/petsc4py.PETSc.c:5192) TypeError: Cannot cast array data from dtype('int64') to dtype('int32') according to the rule 'safe'

I am indexing the PETSc.Mat A with an array c ( numpy.ndarray with dtype('int64')). I assume there is a simple solution (allowing the cast, making everything 32 or 64 bit...). Can you point me in the right direction? Thanks. Chris
