The usual: interface change in PETSc (DMDASetDim renamed to DMDASetDimension) that hasn't been updated in petsc4py yet. The PETSc revision introducing that change is c73cfb54. On 24/08/14 16:27, Cotter, Colin J wrote:
Dear Firedrakers, I just updated my petsc and petsc4py using the PyOP2 install instructions, to be precise I did:
sudo PETSC_CONFIGURE_OPTIONS="--download-ctetgen --download-triangle --download-chaco" pip install -U --no-deps git+https://bitbucket.org/petsc/petsc.git#egg=petsc unset PETSC_DIR unset PETSC_ARCH sudo pip install -U --no-deps git+https://bitbucket.org/petsc/petsc4py.git
I then updated and built PyOP2, firedrake too.
Now, upon importing Firedrake, I get:

What's wrong here?
