Remove hardcoded /data/dw/ path in beaver_preprocess_v2.py

[Samar-Khalid]

Description

The beaver_preprocess_v2.py:24 has a hardcoded path /data/dw/:

BEAVER_DATA_PATH = os.path.join(os.path.dirname(__file__), '../../../../data/dw/')

This causes failures when processing datasets other than dw because the dataset name is hardcoded rather than derived from the input parameters.

Expected Behavior

The data path should use the dataset parameter passed to convert_beaver_questions_to_dinsql_format() to dynamically construct the correct path.

Affected File

eval/dinsql/preprocessed_data/beaver_preprocess_v2.py (line 24)
