Unable to decompose 'Suss' with python

[foongminwong]

I'm trying to run bertini_real -E python for Suss. It works using matlab, but not python.

Here's the screen output from my attempt

bertini_real -E python

Testing for a component of dimension 2.

Bertini verified that a witness point is a smooth
point on a 2 dimensional generically reduced component.

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

thank you, i'll try to replicate it and see what's going on. i suspect scaling coefficients are the culprit...
