No attribute suggestions in operators

Hello.

I have a problem with my Rapid Miner installation. Suddenly I get no proposals for attributes I can choose in the operators. If I, for example, choose a "Select Attributes" operator, then the drop down list under "Attribute" is completely blank, but in the past there was a list of attributes from my data set.

 

Anybody who knows why it suddenly does not work?

    Hi mathias,

     

    please verify if your RapidMiner Studio client is actually generating the necessary meta data. Click on the 'Process' menu entry and afterwards make sure 'Validate Automatically' is selected. Some operators require meta data to work properly.

     

    Cheers,

    Marcel

    Thank you Marcel - that made the difference. Validate Automatically was ticked off
