Dear David, I installed python 3.7.0 using the Archer script (slightly modified) and the installation procedure did succeed. Nevertheless, when trying to import firedrake, I get the following error :

It looks like orte_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during orte_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer):

It clearly comes from openMPI but I do not see why it happens since I can run other mpi processes (like "mpirun -n2 ls").
Does mpirun -n 2 python -c "import firedrake" work? On some supercomputers you always have to run MPI-enabled programs via the mpirun system. Lawrence
