Use a HyperTransformer to manage all the transformers you're applying to a multi-column dataset.
Create one by importing it from the
rdtlibrary. There are no parameters.
from rdt import HyperTransformer
ht = HyperTransformer()
There are a variety of ways to load your data into the expected format. The most common case is your dataset being a csv file:
import pandas as pd
customers = pd.read_csv('./datasets/customers.csv')
