The error message that you are seeing arises from an IndexError exception. It appears that the code is trying to access an element at an index that doesn't exist in the data.

The error happens at the line where data[i][j] is trying to access the data. i is the row index and j is the column index. If your data is a 2-dimensional list, this error could be due to either:

• The row i does not exist, or
• The row exists, but the column j does not exist in the i-th row.

The error message specifies index 2 is out of bounds for axis 0 with size 2, so it seems your data only has 2 rows (indexed as 0 and 1), but the script tries to access the row at index 2, which doesn't exist.
