Setting up my PV_PLUGIN_PATH to point to the paraview-5.9/plugins/pvNVIDIAIndeX directory and executing pvbatch with a representation type to use NVIDIA IndeX causes the following error: INDEX exit error: Double IndeX instances are not allowed. ( 0.151s) [pvbatch ] vtkOutputWindow.cxx:76 ERR| nvindex: PVPLN init error: Failed to initialize the NVIDIA IndeX library interface. Running with PARAVIEW_LOG_PLUGIN_VERBOSITY=INFO indicates that ParaView is trying to incorrectly load *two* libraries that are located in the directory pointed to by PV_PLUGIN_PATH, and this seems to trigger a double initialization of IndeX. Folks at NVIDIA have been informed and have confirmed this error. A simple work-around is to recompile ParaView with PARAVIEW_PLUGIN_AUTOLOAD_pvNVIDIAIndeX:BOOL=ON N.B. Running in client-server mode, there is no problem and IndeX is running well.
