Description

I get a TypeError when fitting a categorical column.

What I Did

import pandas as pd
from rdt import HyperTransformer
df = pd.DataFrame({'a': ['a', 'b', 'c']})
df.a = df.a.astype('category')
ht = HyperTransformer()
ht.fit(df)

TypeError: Cannot interpret '0 a 1 b 2 c Name: a, dtype: category Categories (3, object): ['a', 'b', 'c']' as a data type
