There is an ModuleNotFoundError: No module named 'google' error being shown in the 'Accessing data from your Google Drive' session.

Thank you for creating the issue. The error message ModuleNotFoundError: No module named 'google' appears when the notebook is run outside Colab, including when the notebook is executed for the build of the Jupyter Book website. The code will still execute in Colab. Added a note to clarify this.

In addition, added a note in the README file that this notebook (Prediction using Supervised Learning) and the next one (What Causes What? Introduction to Causal inference) require access to safeguarded data and private/secure storage so once data is obtained, it needs to be stored securely on Google Drive and the notebooks should be run as private Colab notebooks (as opposed to public cloud services including MyBinder).
