    Default Error: Problem de-serializing model file using supplied file name!

    Brand-new WEKA user here. I created a model (file with .model extension, right?) in WEKA. I use the "Browse" button to put its path in the "Load/import forecaster" box. Nothing appears in the "Fields mapping" or "Model" tabs. Running the transformation results in "Problem de-serializing model file using supplied file name!". I'm using PDI and WEKA 3.8.

    I have no clue where to go from here. Any help would be appreciated.

    PDI ships with Weka 3.7.11. Models created in 3.8.0 are not compatible I'm afraid. The good news is that you can simply swap the 3.7.11 jar file out of PDI - you'll find it in the lib directory of the weka-forecasting plugin in PDI's plugin directory, it will be named pdm-3.7-*.jar - and replace it with the weka.jar file that comes with Weka 3.8.0. Alternatively, you can download Weka 3.7.11 and recreate your forecasting model.
