I am trying to run contextual MAB algo by creating this learner: static VWActionProbsLearner learner = VWLearners.create("--cb_explore_adf -q UA --softmax --lambda 20 --noconstant --permutations --learning_rate 0.8 --readable_model path.txt --invert_hash path_1.txt -f saved_model.vw --holdout_off --early_terminate 2");
After this, I am trying to predict using this command: ActionProbs[] testPreds = new ActionProbs[]{learner.predict(vwTextExample)};
While calling this, I am getting error: Getting error 'java/lang/NoClassDefFoundError': vowpalWabbit/responses/ActionProb
