Example 1: Remove the deployed data from the table within the AutoDataPrep object

from teradataml import AutoDataPrep

Load the example data.

>>> load_example_data("teradataml", "titanic")
    >>> titanic = DataFrame.from_table("titanic")

Create an instance of AutoDataPrep.

>>> aprep_obj = AutoDataPrep(task_type="Classification", verbose=2)

Fit the data.

>>> aprep_obj.fit(titanic, titanic.survived)

Deploy the data to the database.

>>> aprep_obj.deploy("table_name")

Remove lasso deployed data from the table.

>>> aprep_obj.delete_data("table_name", fs_method="lasso")

Example 2: Remove the deployed data from the table using different instance of AutoDataPrep object

Create an instance of AutoDataPrep.

>>> aprep_obj2 = AutoDataPrep()

Remove lasso and pca deployed data from the table.

>>> aprep_obj2.delete_data("table_name", fs_method=["lasso", "pca"])
