Problem Description
When using this simple piece of code, I have a warning:
from sklearn.datasets import make_classification
from skrub import tabular_pipeline
df, y = make_classification(random_state=42)
estimator = tabular_pipeline("classification")
estimator.fit(df, y)
The warning says:
UserWarning: Only pandas and polars DataFrames are supported, but input is a Numpy array. Please convert Numpy arrays to DataFrames before passing them to skrub transformers. Converting to pandas DataFrame with columns ['0', '1', …].
warnings.warn(
I don't really understand the point of the warning, because it doesn't seem to be a problem at all.
Feature Description
What about removing the warning since having a numpy array as input doesn't seem to be a problem, at least in that use case with only one column, and doesn't call for a user action?
I'm also surprised by the fact that it seems to mention only the input y - why isn't df also a problem?
Alternative Solutions
Be more explicit about the consequences of automatic conversion. Otherwise as a user, I'm very tempted to turn off warning notifications.
Additional Context
No response
