n this problem, we will read in and process a data file containing two decimal values in each line. The first value
is intended to represent an observed value of some random variable, while the second value is intended to
represent a prediction generated by some model. We will use these values to calculate the sum of squared
errors score for the predictions.
The path for the data file we will be using in this problem is /FileStore/tables/pairs_data.txt. We will
start by reading the data file and counting the number of records.
Complete the following steps in a single code cell:
1. Read the contents of the data file into and RDD named pairs_raw.
2. Display the number of elements contained in the pairs_raw RDD
