Hi Robert
The example works when I change the ls solver from scipy_direct to scipy_iterative. Not when I uninstall scikit-umfpack. It is apparently not being defaulted to scipy LU solver. Any thoughts on this? However, I am
If you remove scikit-umfpack and still see the same error, I would guess you have another version of scikit-umfpack installed somewhere.
unable to specifiy the number of iterations if I change to scipy_iterative.
See examples/diffusion/cube.py for an example of how to set the number of iterations.
The UMFPACK has to be installed before using sckit-umfpack. There is no good documentation on that . I got onto this website: http://faculty.cse.tamu.edu/davis/suitesparse.html . However it is only available for MATLAB and C.
How did you install python and other sfepy dependencies? (Which versions?) The easiest way nowadays is to use anaconda - there is even a recipe for sfepy on conda-forge ("conda install -c conda-forge sfepy" should work).
