Hi Neha

This generally occurred when , you training data set have some value of
categorical variable ,which in not there in your testing data. For e.g you
have column DAYS ,with value M,T,W in training data . But when your test
data contains F ,then it say no key found exception .  Please look into
this  , and if that's not the case ,then Could you please share your code
,and training/testing data for better understanding.

Regards
Pralabh Kumar
