3. Preparing Data for Predictive Modeling

Activity 3.01: Preparing to Train a Predictive Model for Employee Retention

Solution:

1. Check the head of the table by running the following command:

   %%bash
   head ../data/hr-analytics/hr_data.csv

   Note how we specify paths relative to the notebook's location. In this case, we need to step back one directory (by using ".." in the file path), which brings us to the root folder for the project. Then, we look in data/hr-analytics for hr_data.csv.

   This will generate the following output:

2. If you cannot run bash in your notebook, run the following command:

   with open('../data/hr-analytics/hr_data.csv', 'r') as f:
       for _ in range(10):
           print(next(f).strip())

   The output is as follows:

   Judging by the output, convince yourself that it...
