**Bug Report / Data Issue: Buchwald-Hartwig dataset size mismatch**

[Tuesdayand]

Hi TDC team,

I noticed a discrepancy between the dataset statistics listed on the TDC website and the actual data returned by the API.

Website states: 55,370 reactions
Actual data returned: ~3,955 reactions

Reproduction steps:

from tdc.single_pred import Yields
import pandas as pd

data = Yields(name='Buchwald-Hartwig')
split = data.get_split()
df_all = pd.concat([split['train'], split['valid'], split['test']], ignore_index=True)
print(len(df_all))  # returns 3955

Questions:

1. Is the 55,370 figure referring to an augmented version of the dataset (e.g., SMILES enumeration)?
2. If so, is there a way to download the augmented version (55,370 reactions) through the TDC API?
3. If not, could you update the dataset statistics on the website to reflect the correct number?

Thank you!
