<div>I'm using the binary version of Paraview available in

there,
<div><br></div>
<div>I see an old thread here: <a href="https://paraview.markmail.org/thread/z7cy73444s7fjadk" target="_blank">https://paraview.<wbr>markmail.org/thread/<wbr>z7cy73444s7fjadk</a> about
setting multiple input ports for python programmable filters but I
cannot get this to work.</div>
<div><br></div>
<div>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 <wbr>vtkPythonProgrammableFilter.</div>
<div><br></div>
<div>I see that in
`paraview/ParaViewCore/<wbr>ClientServerCore/Core/<wbr>vtkPythonProgrammableFilter.h`
the following is declared:</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div>
<div> /**</div>
</div>
<div>
<div> * Set the number of input ports</div>
</div>
<div>
<div> * This function is explicitly exposed to enable a
vtkClientServerInterpreter to call it</div>
</div>
<div>
<div> */</div>
</div>
<div>
<div> void SetNumberOfInputPorts(int numberOfInputPorts)
VTK_OVERRIDE</div>
</div>
<div>
<div> {</div>
</div>
<div>
<div>
this->Superclass::<wbr>SetNumberOfInputPorts(<wbr>numberOfInputPorts);</div>
</div>
<div>
<div> }</div>
</div>
</blockquote>
<div><br></div>
<div>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:</div>
<div><br></div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">

<div>
<div>name="TestMuliPort” </div>
</div>
<div>
<div>class="<wbr>vtkPythonProgrammableFilter” </div>
</div>
<div>
<div>label=“TestMuliPort”</div>
</div>
<div>
<div>post_creation=“<wbr>SetNumberOfInputPorts"</div>
</div>
<div>
<div>arguments="2”></div>
</div>
<div>……..</div>
</blockquote>
<div><br></div>
<div>I get the following ERROR:</div>
