<br>In your XML, instead of using `post_creation` and `argument`
<br>attributes, just add a `input_ports="2"` attribute.
<br>
<br>BTW, on-going work on Python algorithm will make this much easier. In
<br>this example [1], one could simply pass in `nInputPorts=2` to require
<br>two input ports. I plan to add example with multiple input ports
<br>before this MR [2] gets merged.

<br>> Hi Gaël,
<br>>
<br>> Thank you for your help! I was aware of this way to add multiple inputs to a programmable filter and FYI if you would like to have a dialog appear in the PV GUI to select the inputs in a non-arbitrary order then try making several InputProperty attributes in the XML rather than using the multiple_input variable.
<br>>
<br>> Unfortunately, this still does not address my original issue. I need the inputs to each be on their own port rather than multiple connections on a single port. This is because I will implement the ability to select input arrays from each port via drop down menus.
<br>>
<br>> Does anyone know how to give the vtkPythonProgrammableFilter multiple input ports or a means to select input arrays to process when having multiple connections on one port? I have a robust means of selecting input arrays for just one input but I cannot get it to work for more than one input.
<br>>
<br>> Thank you,

<br>>> Hi there,
<br>>>
<br>>> I see an old thread here: <a href="https://paraview.markmail.org/thread/z7cy73444s7fjadk">https://paraview.markmail.org/thread/z7cy73444s7fjadk</a> about setting multiple input ports for python programmable filters but I cannot get this to work.
<br>>>
<br>>> I want to declare multiple input ports in a ServerManagerConfiguration XML plugin but I have been unable to successfully add more than one input port to the vtkPythonProgrammableFilter.
<br>>>
<br>>> I see that in `paraview/ParaViewCore/ClientServerCore/Core/vtkPythonProgrammableFilter.h` the following is declared:
<br>>>
<br>>> /**
<br>>> * Set the number of input ports
<br>>> * This function is explicitly exposed to enable a vtkClientServerInterpreter to call it
<br>>> */
<br>>> void SetNumberOfInputPorts(int numberOfInputPorts) VTK_OVERRIDE
<br>>> {
<br>>> this->Superclass::SetNumberOfInputPorts(numberOfInputPorts);
<br>>> }
<br>>>
<br>>>
<br>>> This leads me to believe that the functionality is there, but how exactly would I set the number of input ports from an XML plugin for a Programmable Filter? I have tried the following with no luck:
<br>>>
<br>>> <ServerManagerConfiguration>
<br>>> <ProxyGroup name="filters">
<br>>> <SourceProxy
<br>>> name="TestMuliPort”
<br>>> class="vtkPythonProgrammableFilter”
<br>>> label=“TestMuliPort”
<br>>> post_creation=“SetNumberOfInputPorts"
<br>>> arguments="2”>
<br>>> ……..
<br>>>
<br>>>
<br>>> I get the following ERROR:
<br>>>
<br>>> ERROR: In /Users/kitware/dashboards/buildbot-slave/8275bd07/build/superbuild/paraview/src/ParaViewCore/ServerImplementation/Core/vtkPVSessionCore.cxx, line 371
<br>>> vtkPVSessionCore (0x60c0000d4510): Object type: vtkPythonProgrammableFilter, could not find requested method: "SetNumberOfInputPorts"
