本文说明如何将运行时统计信息添加到Tensorboard:
run_options = tf.RunOptions(trace_level=tf.RunOptions.FULL_TRACE)
run_metadata = tf.RunMetadata()
summary, _ = sess.run([merged, train_step],
feed_dict=feed_dict(True),
options=run_options,
run_metadata=run_metadata)
train_writer.add_run_metadata(run_metadata, 'step%d' % i)
train_writer.add_summary(summary, i)
print('Adding run metadata for', i)

这在单台机器上相当简单.如何使用Estimators在分布式环境中执行此操作?
我正在使用节点Bigquery Package来运行简单的作业。查看工作的结果(例如data),effective_date属性如下所示:
effective_date: BigQueryDate { value: '2015-10-02' }

这显然是返回data对象中的一个对象。
将返回的json导入Firestore会产生以下错误:
UnhandledPromiseRejectionWarning: Error: Argument "data" is not a
valid Document. Couldn't serialize object of type "BigQueryDate".
Firestore doesn't support JavaScript objects with custom prototypes
(i.e. objects that were created via the 'new' operator).

有没有一种优雅的方式来解决这个问题?是否需要遍历结果并转换/删除所有对象?

ADC(应用程序默认凭据)工作流程是否仅支持 Google Cloud API(例如,支持 Google Cloud Storage API,但不支持 Google Sheet API)?
我指的是google.auth 的默认方法- 不必在代码中存储任何私钥是一个巨大的胜利,也是有效利用 ADC(应用程序默认凭据)设置的主要好处。
GOOGLE_APPLICATION_CREDENTIALS如果我将环境变量设置为私钥文件(例如 key.json),则以下代码将有效。default这与包中步骤 1 的方法一致google.auth: 1. If the environment variable GOOGLE_APPLICATION_CREDENTIALS is set to the path of a valid service account JSON private key file, then it is loaded and returned.
import google.auth
from apiclient import discovery
credentials, project_id = google.auth.default(scopes=['https://www.googleapis.com/auth/spreadsheets'])
sheets = discovery.build('sheets', 'v4', credentials=credentials)
SPREADSHEETID = '....'
result = sheets.spreadsheets().values().get(spreadsheetId=SPREADSHEETID, range='Sheet1!A:B').execute()
print result.get('values', [])

现在,看看该方法的第 4 步: …
python google-authentication google-compute-engine google-cloud-platform google-sheets-api
我想知道是否可以将my-project-a中创建的服务帐户附加到my-project-b中的 Google Compute Engine 实例?
以下命令:
gcloud beta compute instances create my-instance \
--service-account=my-service-account@my-project-a.iam.gserviceaccount.com \
--scopes=https://www.googleapis.com/auth/cloud-platform \
--project=my-project-b

给我以下错误:

不确定这是否相关,但查看 UI(在my-project-b中),没有选项可以从任何其他项目添加服务帐户。我希望能够添加帐户my-service-account@my-project-a.iam.gserviceaccount.com
有没有办法在Google BigQuery Repeated字段中选择前n个项目?
查看Google文档中的示例:
WITH items AS
(SELECT ["apples", "bananas", "pears", "grapes"] as list
UNION ALL
SELECT ["coffee", "tea", "milk" ] as list
UNION ALL
SELECT ["cake", "pie"] as list)
SELECT list, list[OFFSET(0)] as offset_1, list[OFFSET(1)] as offset_2
FROM items;

OFFSET()函数返回一个(非重复)元素。
有没有一种优雅的方法来选择重复字段中的前n个元素(例如n = 2)?查看第1行,输出应为包含两个元素的重复字段:苹果和香蕉。
