Attempting to use an MPI routine before initializing MPICH
The message in the title is displayed when launching ParaView built with MPICH.
The problem has been reproduced with a smaller program: TaskParallelism, in the examples.
This error arise when the program is linked with libvtkRemotingViewsPython-pv5.11.so, but there is no error without this library.
Note: I know that this code belongs to ParaView and not VTK, and I firstly reported this issue at paraview/paraview#22256 (closed) (more details are available there), but since this code comes from VTK, I have been asked to report it here.
