error installing PyOP2

Any idea what's going on?
This doesn't immediately look like a PyOP2 related problem. Rather some mismatch between MPI pieces. Does the following work? python -c "import petsc4py; petsc4py.init()" If not, can you compile and run C-based PETSc programs (using the same PETSC_DIR/PETSC_ARCH combo) ?

Doing the latest pull of PyOP2, I ran:
make test
And got these errors:

This is a different error now. Do you know what the problem is now?
Thanks, Justin

Any idea what's going on?
This doesn't immediately look like a PyOP2 related problem. Rather some mismatch between MPI pieces.
Does the following work?
python -c "import petsc4py; petsc4py.init()"
If not, can you compile and run C-based PETSc programs (using the same PETSC_DIR/PETSC_ARCH combo) ?
Cheers,
Lawrence

should I have run something else?
No, this is correct. Let's check at point this is failing (I think it's failing early). Does python -c "import pyop2; pyop2.init(); print pyop2.__version__" work? Can you show also the output of the following: ldd pyop2/sparsity.so ldd /path/to/petsc4py/PETSc.so ldd /path/to/petsc/libpetsc.so ?

No, this is correct.
Let's check at point this is failing (I think it's failing early).
Does
python -c "import pyop2; pyop2.init(); print pyop2.__version__"
work?
Can you show also the output of the following:
ldd pyop2/sparsity.so ldd /path/to/petsc4py/PETSc.so ldd /path/to/petsc/libpetsc.so
?

Error in atexit._run_exitfuncs:
Sorry for these continued pains! So PyOP2 imports cPickle elsewhere, so I think this module most exist. Plausibly the "six" module on your system is not sufficiently up-to-date. Does the following fail: python -c "from six.moves.cPickle import dumps" If that works, I'm very confused, but I suspect it won't. If it doesn't work, can you try installing an updated "six" module: pip install --user six and then go again.

Lawrence, Upgrading "six" resolved that issue. However, when I attempt to run my mixed-poisson.py I get this error: Traceback (most recent call last): File "mixed-poisson.py", line 79, in <module> solver_parameters=selfp_parameters) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/variational_solver.py", line 231, in __init__ super(LinearVariationalSolver, self).__init__(*args, **kwargs) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/variational_solver.py", line 110, in __init__ ctx = solving_utils._SNESContext(problem) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/solving_utils.py", line 105, in __init__ for problem in problems) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/solving_utils.py", line 105, in <genexpr> for problem in problems) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/assemble.py", line 67, in assemble inverse=inverse, nest=nest) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/assemble.py", line 100, in _assemble inverse=inverse) File "/Users/justin/Software/firedrake-deps/firedrake/firedrake/ffc_interface.py", line 285, in compile_form ffc_kernel = FFCKernel(f, name + str(i) + str(j), parameters) File "/usr/local/lib/python2.7/site-packages/PyOP2-0.11.0_368_g6ee644d-py2.7-macosx-10.10-x86_64.egg/pyop2/caching.py", line 201, in __new__ return cls._cache_lookup(key) File "/usr/local/lib/python2.7/site-packages/PyOP2-0.11.0_368_g6ee644d-py2.7-macosx-10.10-x86_64.egg/pyop2/caching.py", line 253, in _cache_lookup return cls._cache.get(key) or cls._read_from_disk(key) File "/usr/local/lib/python2.7/site-packages/PyOP2-0.11.0_368_g6ee644d-py2.7-macosx-10.10-x86_64.egg/pyop2/caching.py", line 279, in _read_from_disk val = cPickle.loads(val) AttributeError: 'module' object has no attribute 'ColSparseArrayInit' This was after pulling the latest PyOP2 and firedrake repositories.

Hi Justin,

Coming back to this.
I believe I have puled the latest petsc, petsc4py, and PyOP2 repositories onto my laptop. Following through with all the (re)installation, I come across this error when I run 'make test' in PyOP2:
Error in atexit._run_exitfuncs:
Sorry for these continued pains!
So PyOP2 imports cPickle elsewhere, so I think this module most exist. Plausibly the "six" module on your system is not sufficiently up-to-date.
Does the following fail:
python -c "from six.moves.cPickle import dumps"
If that works, I'm very confused, but I suspect it won't.
If it doesn't work, can you try installing an updated "six" module:
pip install --user six
and then go again.
