Quantconnect Popular Libraries XGBoost Page

So I was checking out Quantconnect's example demo code for XGBoost in Python from

(https://www.quantconnect.com/docs/v2/writing-algorithms/machine-learning/popular-libraries/xgboost#09-Clone-Example-Algorithm). 

However, I when I cloned the demo and tried running the backtest with the code unchanged, I keep on receiving the error 

"During the algorithm initialization, the following exception has occurred: Can't get attribute 'NeuralNetwork' on  at _getattribute".

I tried asking Mia AI but couldn't find a working solution. I'm pretty new to machine learning libraries so I'm stuck on this one.
