Problem with Model Loader

Jorge

Hi!

I'm having problems with my application and I don't know how to solve it

My XML process is that:

<?xml version="1.0" encoding="windows-1252"?>
<process version="4.4">
  <operator name="Apply" class="Process" expanded="yes">
      <parameter key="logverbosity"	value="init"/>

          </operator>
          <operator name="ChangeAttributeRole" class="ChangeAttributeRole">
              <parameter key="name"	value="Trust"/>
              <parameter key="target_role"	value="label"/>
          </operator>
          <operator name="ExampleFilter" class="ExampleFilter">
              <parameter key="condition_class"	value="missing_labels"/>
              <parameter key="invert_filter"	value="false"/>
          </operator>

              <parameter key="random_seed"	value="2001"/>
              <parameter key="encoding"	value="SYSTEM"/>
              <operator name="Numerical2Polynominal" class="Numerical2Polynominal">

                  <parameter key="create_view"	value="false"/>
              </operator>
          </operator>
          <operator name="ChangeAttributeRole (3)" class="ChangeAttributeRole">
              <parameter key="name"	value="Trust"/>
              <parameter key="target_role"	value="prediction"/>
          </operator>
      </operator>
      <operator name="ModelLoader" class="ModelLoader">
          <parameter key="model_file"	value="C:\Algoritmo definitivo\model.mod"/>
      </operator>
      <operator name="ModelApplier" class="ModelApplier">
          <parameter key="keep_model"	value="false"/>
          <list key="application_parameters">

      <operator name="AttributeFilter" class="AttributeFilter">

          <parameter key="example_set_file"	value="C:\Algoritmo definitivo\definitivo.xrff"/>
      </operator>
  </operator>
</process>

When I execute that:

 RapidMiner.init();
                
                File f = new File("Trust.xml");
                try {
                        Process process = new Process(f);
                        process.run();


                } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                } catch (XMLException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                }

The execution, when arrives to that point

   <operator name="ModelLoader" class="ModelLoader">
          <parameter key="model_file"	value="C:\Algoritmo definitivo\model.mod"/>
      </operator>

Gives me that error:

Can anyone help me?

Thanks,

I solved it! :P

The model was in xml...

With the model in binary type don't throws that exception
