Sampling with HMA Synthesizer generates many SingleTableMetadata deprecation warnings

[srinify]

Environment Details

• SDV version: 1.17.1 (latest)

Error Description

When sampling using an HMA Synthesizer object that was instantiated using a MultiTableMetadata object, the SingleTableMetadata deprecation warning is repeatedly logged:

This warning isn't very helpful (as it describes the SingleTableMetadata object) and repeats many times (it loosely seems like a larger volume of data generates more warnings). The user is already shown an accurate warning during synthesizer instantiation:

/usr/local/lib/python3.10/dist-packages/sdv/multi_table/base.py:110: FutureWarning: The 'MultiTableMetadata' is deprecated. Please use the new 'Metadata' class for synthesizers.
  warnings.warn(DEPRECATION_MSG, FutureWarning)

Steps to reproduce

Internal Colab Notebook to reproduce

from sdv.datasets.demo import download_demo
from sdv.metadata import MultiTableMetadata
from sdv.multi_table import HMASynthesizer

data, metadata = download_demo(
    modality='multi_table',
    dataset_name='fake_hotels'
)

guests_table = data['guests']
hotels_table = data['hotels']

multi_metadata = MultiTableMetadata()
multi_metadata.detect_from_dataframes(data)

synthesizer = HMASynthesizer(multi_metadata)
synthesizer.fit(real_data)
synthetic_data = synthesizer.sample()
