認証 - 計算エンジンからdatalabに接続

Question

datalabからbigQueryに接続し、更新コマンドを実行したいと思います。 は、私はAPI &認証のための次のコードを実行します。

from google.cloud import bigquery 

# Get everything we possibly can from the service account JSON file 
#set GOOGLE_APPLICATION_CREDENTIALS 
cred = bigquery.Client.from_service_account_json('OrielResearch-da46e752c7ff.json') 
# Instantiates a client 
client = bigquery.Client(project='speedy-emissary-167213',credentials=cred) 
# The name of the dataset 
dataset_name = 'pgp_orielresearch' 
# The name of the table 
table_name = 'update_queries' 
# Perform a synchronous query. 
QUERY = (
    'SELECT * FROM [speedy-emissary-167213:pgp_orielresearch.update_queries]') 
query = client.run_sync_query(QUERY) 
dataset = client.dataset(dataset_name) 
tables, token = dataset.list_tables() 

をし、次のエラーを取得： はAttributeError：「クライアント」オブジェクトが属性を持っていない

「を承認する」任意のアイデアを？

フルスタックは、次のとおりです。

はそうのような資格情報を設定しよう：

import os 
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = 'OrielResearch-da46e752c7ff.json' 
from google.cloud.bigquery.client import Client 

client = Client()
