Hi, I am using BigQuery API : bigquery.SourceFormat.PARQUET to load parquet data from GCS to BigQuery table.

At line:
job_config = bigquery.LoadJobConfig()
job_config.source_format = bigquery.SourceFormat.PARQUET

it throws an error -
AttributeError: 'module' object has no attribute 'SourceFormat'

Environment specs are here:

    client = bigquery.Client()
    dataset_id = 'dataset_01'
    dataset_ref = client.dataset(dataset_id)
    job_config = bigquery.LoadJobConfig()
    job_config.source_format = bigquery.SourceFormat.PARQUET
    load_job = client.load_table_from_uri(
        'gs://xxxx/xxx/*.parquet',
        dataset_ref.table('tablexxx'),
        job_config=job_config)
    assert load_job.job_type == 'load'
