I want to bulid paraview on windows, does anyone know whether or not windows support mpi4py? If windows support mpi4py, how can I add it? Thanks in advance.

You can install mpi4py yourself using pip. What’s not supported is VTK/ParaView building mpi4py for you on that branch/release. It is supported on master and that will be 5.7.

Thanks Ben, I see the official windows release paraview-5.6 has mpi4py, so I can use the full feature of “Find Data”. If I want to build windows paraview-5.6 from scratch, how can I do that?
