试图在谷歌应用引擎python上使用大查询。我试图使用this client library来实现这一点。我已经导入了所有必要的库，并以某种方式运行下面的代码段
from bigquery import get_client
# BigQuery project id as listed in the Google Developers Console.
project_id = 'project_id'
# Service account email address as listed in the Google Developers Console.
service_account = 'my_id_123@developer.gserviceaccount.com'
# PKCS12 or PEM key provided by Google.
key = 'key.pem'
client = get_client(project_id, service_account=service_account,
private_key_file=key, readonly=True)
并仍然收到错误：
