Hi guys,

I'm having a problem with predictor preparator in dryrun. Keras predictor needs 
to convert images to nparray, a type wich its not json serializable.  I've 
tried to convert the nparray to a python list, but this doesn't work well 
because it is a multidimensional array. Any ideas on how to solve this?

 

Thanks.
