We are trying to adapt sfepy for mechanobiological tissue modeling at Yeditepe University, Istanbul. 

We are primarily using the arch (linux-x64) platform for our work. Python 3.5 and 2.7.11 are already installed in our systems. Building and installing sfepy somehow worked, though without mayavi. I believe mayavi does not install as a result of version incompatibilities with vtk and python 2.7.

Is a virtual environment more suitable for sfepy, and what are the preferred versions of dependencies (python, vtk, and mayavi)?

Thanks,

Fethi

Hi Nina,

could you try mayavi 4.3? The version 4.4 is not compatible with sfepy for the
moment (cf. [1]).
