Multilabel Text Classification Each CSV file can have any number of columns, but only two will be used by the model. Those columns are specified by the parameters dataset.text_column_name (if not modified, the default value is text) and dataset.target_column_name (if not modified, the default value is label). For example, a single CSV file can look like this:
