----------------------------------------------------------------------
model=joblib.load('project21-carcomforttype.obj')
----------------------------------------------------------------------
Final_predictions=model.predict(x_test)
Final_predictions=pd.DataFrame(Final_predictions,columns=['unacc(0),acc(1),good(2),vgood(3)'])
Final_predictions[:5]
----------------------------------------------------------------------
Final_predictions.sample(n=10)
--------------------------------------------------------------------
#Saving final predictions in file.csv format
Final_predictions.to_csv('E:\\final_predictionscarcomforttype',index=False)
