The error message "KeyError: '['Unnamed: 0'] not found in axis'" is indicating that the column 'Unnamed: 0' does not exist in the dataset. This could be due to a typo in the column name or the column has already been dropped previously.

To avoid this error, you can check the column names in the dataset before dropping a column to ensure that the column exists. You can use the dataset.columns attribute to get a list of all column names in the dataset.
