• Python 2 or 3
• NLopt
• Numpy
• Matplotlib
• CVXOPT
• PyOpenCL

You need to compile and install NLopt with its Python bindings. Moreover, you will also need PyOpenCL to run the OpenCL PatchMatch code used by the appearance function. Cholmod (through CXVOPT) is used for the solving the linear system in the FEM elasticity problem. MMA (through NLopt) is used to solve the constrained non-linear minimization problem.
