Hi,

trying to write the model "Nominal2Numerical" to disk via the ModelWriter leads to the error message:

P Jul 8, 2009 2:10:46 PM: [Error] ModelWriter: ModelWriter: ModelWriter: Missing input: Model
P Jul 8, 2009 2:10:46 PM: [Error] There was 1 error.

Here is my process:
Code:
<operator name="Root" class="Process" expanded="yes">
    <description text="#ylt#p#ygt#The normalization operator supports both z-transformation on zero mean with standard deviation 1 and range normalization into a predefined range. #ylt#/p#ygt#"/>
    <operator name="ArffExampleSource" class="ArffExampleSource">
        <parameter key="data_file" value="../data/iris.arff"/>
        <parameter key="label_attribute" value="class"/>
    </operator>
    <operator name="Nominal2Numerical" class="Nominal2Numerical">
        <parameter key="return_preprocessing_model" value="true"/>
    </operator>
    <operator name="ModelWriter" class="ModelWriter">
        <parameter key="model_file" value="norm.mod"/>
    </operator>
</operator>

The model is however written to disk and seems to be OK. Is this error
message possibly redundant?

I'm using RapdiMiner v4.4.0

Regards,
Paul

Hi Paul,

Thanks for the hint. It's a bug and will be fixed in the next release. It concerns only the validation of the process, not the process execution itself.

Cheers,
Simon
