The One-Hot-Encoder can be fitted without naming the columns that need to be encoded. In that case it is applied to all columns of the table. Usually you only apply the One-Hot-Encoder to a few columns of a table, however. This applies to other table transformers, too.
Desired solution
Change the parameter
column_namesto be a required parameter.Possible alternatives (optional)
