Fixes #7407

Just adding in a final metric of accuracy to declare...

Describe your change:

I have imported another module from sklearn.metrics library i.e. accuracy_score to display the final accuracy of the trained model out on the console. Also, just to make it a little propped up, I also imported the time library and stopped the code-execution at two points in the middle (this won't affect the final accuracy of the model in any way).
