FEniCS installed from source does not work with scipy?

+1 vote

In order to use FEniCS 1.5 on debian I've installed from source using

curl -s http://fenicsproject.org/fenics-install.sh | bash

and source fenics.stable. It works fine except i am no longer able to use the scipy module. If i try to import it, i get the error:

ImportError: No module named scipy

Any hints on how to use scipy with FEniCS installed from source?

The reason is that sourcing fenics.stable will set your PYTHONPATH to point to the directory where fenics-install.sh puts its Python installation (located in a folder under ~/.hashdist).

It should work to add your default Python installation at the end of your PYTHONPATH like so:

export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/site-packages

(Adjust to where Python is located on your machine.)

Added 

export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/dist-packages

to make it work. Thanks!

I have the same issue on my Mac.

In my Mac OS, it has neither /usr/lib/python2.7/site-packages nor /usr/lib/python2.7/dist-packages. Any reason?

If I just add path "/usr/bin" where the system python is, it still does not work.
