keras model / deep learning

1   Im trying to use the Iris data set  and  the respective deep learning process  given in Rapidminer repository , under 'keras sample" - iris data set..
But im not able to execute the same.  But I couldnt do it, with warning of " process failed'.   ( please find enclosed the process jpg).  i tried with some other data set, the issue remains.  can you help me to resolve this. thanks.
