Hi,
I installed all components of Fenics from source on a Linux
cluster. The installation completed but on trying to run
demo_poisson.py, I get an unexplained error. Please advise. Below is
detailed information. I can provide further information as requested.
Thanks a lot in advance

12) swig/3.0.7 15) cmake/3.3.0
Note: Could it be because I built Fenics with Python 2.7.10? Thats the
optimized Python build on this cluster as of now. I read that the
recommended Python version for Fenics is 2.7.5 but I would rather not
rebuild Python ( and numpy), unless absolutely necessary.
