AttributeError：“客户端”对象没有属性“ load_table_from_storage”

Question

对此我还很陌生，我想尝试使用数据流将数据从云存储中的csv数据加载到Bigquery。但是我遇到了以下错误。请建议我做一个更好的方法。在此先感谢

我正在Linux服务器上运行，python版本是3.x。

AttributeError: 'Client' object has no attribute 'load_table_from_storage'

import argparse
import uuid
import pprint
from google.cloud import bigquery

dataset_name = 'XXX'
table_name = 'XXX'
source = "Input filepath"
format = 'CSV'

def load_data_from_gcs(dataset_name, table_name,  source):
    bigquery_client = bigquery.Client()
    dataset = bigquery_client.dataset(dataset_name)
    table = dataset.table(table_name)
    job_name = str(uuid.uuid4())

    job = bigquery_client.load_table_from_storage(
        job_name, table, source)

    job.source_format = format
    job.begin()
    job.result()
    print (job.result)

    print('Loaded {} rows into {}:{}.'.format(
        job.output_rows, dataset_name, table_name))

if __name__ == '__main__':
    parser = argparse.ArgumentParser(
        description=__doc__,
        formatter_class=argparse.RawDescriptionHelpFormatter)
    parser.add_argument('XXX')
    parser.add_argument('XXX')
    parser.add_argument('CSV')

    args = parser.parse_args()

    load_data_from_gcs(
        args.dataset_name,
        args.table_name,
        args.source)

load_data_from_gcs(dataset_name, table_name, source)
