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?
