ParaView Support

Hello, I have a problem when I try to start trace on ParaView:

ERROR: In …/Remoting/ServerManager/vtkSMTrace.cxx, line 76
vtkSMTrace (0x55729dff7040): Failed to import paraview.smtrace module.
Generic Warning: In …/Remoting/ServerManager/vtkSMTrace.cxx, line 162

Trace not started since required Python modules are missing.

Anyone could help me please?
thanks

Which version, downloaded from where, of ParaView, are you using ?
