Dear firedrakers, I get a strange error message when I run ./scripts/firedrake-clean (branch multigrid-parallel, just pulled from remote): eikemueller@138-38-169-12 $ ./scripts/firedrake-clean Traceback (most recent call last): File "./scripts/firedrake-clean", line 3, in <module> from firedrake.ffc_interface import clear_cache, FFCKernel File "/Users/eikemueller/PostDocBath/EllipticSolvers/firedrake/firedrake/__init__.py", line 2, in <module> import petsc File "/Users/eikemueller/PostDocBath/EllipticSolvers/firedrake/firedrake/petsc.py", line 4, in <module> petsc4py.init(sys.argv) File "/Users/eikemueller/PostDocBath/EllipticSolvers/petsc4py/arch-darwin-c-opt/lib/python2.7/site-packages/petsc4py/__init__.py", line 42, in init PETSc = petsc4py.lib.ImportPETSc(arch) File "/Users/eikemueller/PostDocBath/EllipticSolvers/petsc4py/arch-darwin-c-opt/lib/python2.7/site-packages/petsc4py/lib/__init__.py", line 29, in ImportPETSc return Import('petsc4py', 'PETSc', path, arch) File "/Users/eikemueller/PostDocBath/EllipticSolvers/petsc4py/arch-darwin-c-opt/lib/python2.7/site-packages/petsc4py/lib/__init__.py", line 64, in Import module = imp.load_module(fullname, fo, fn, stuff) File "PETSc.pyx", line 100, in init petsc4py.PETSc (src/petsc4py.PETSc.c:221273) RuntimeError: module compiled against API version 9 but this version of numpy is 7 This is odd, because I just recompiled petsc4py (git pull; make clean; python setup.py install --prefix=`pwd`/$PETSC_ARCH).
