Error during deploy
I'm working on a modified version of Text Classification Engine (I started
with the Text Classification Engine Tutorial
predictionio.incubator.apache.org/demo/textclassification/ and i modified
the case class Query and the other classes accordingly)
Build and training are successful, but when I deploy I get this error:

Not sure what this error is about; I am not including any code because I'm
not sure where the issue is. Hope you can help.

Hey Emilio,
How are you storing your model? Failing to invert means it cannot
deserialize your model from disk. It's definitely an error message that we
could improve.
Regards,
Donald
