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.
