The data we'll be using comes from a Kaggle … Webimages in a string column. It should include other column/s. depending on the `class_mode`: - if `class_mode` is `"categorical"` (default value) it must. include the `y_col` column with the class/es of each image. Values in column can be string/list/tuple if a single class. or list/tuple if multiple classes.
