Answer 1

Your code is perfect. I am guessing your stocker installation was incorrect, as the code is running fine in my system.

If you are using Anaconda distribution you can follow these commands:

conda install quandl numpy pandas matplotlib pystan

conda update quandl numpy pandas matplotlib pystan

Or else:

pip install -U quandl numpy pandas fbprophet matplotlib pytrends pystan

This is the output of your code:
