Kubeflow sdk - ошибка в client.list_experiments()

Question

Kubeflow sdk - ошибка в client.list_experiments()

Я следую примеру в документации (https://www.kubeflow.org/docs/components/pipelines/sdk/connect-api/), но получаю сообщение об ошибке при попытке доступа к экспериментам или запускам (при попытке перечислить и / или создать их)

Я перенаправил порт на ml-pipeline-ui:

      kubectl port-forward svc/ml-pipeline-ui 3000:80 --namespace kubeflow

Следующее приводит к ошибке:

      import kfp
client = kfp.Client(host='http://localhost:3000')
print(client.list_experiments())

Ошибка, которую я получаю client.list_experiments():

Однако перечисление конвейеров работает:

      import kfp
client = kfp.Client(host='http://localhost:3000')
print(client.list_pipelines())

Я убедился, что переадресация портов работает - я могу получить доступ к пользовательскому интерфейсу по адресу http: // localhost: 3000 / и могу видеть конвейеры. Есть идеи, где я ошибаюсь с экспериментами? Пример в документации кажется довольно простым, но что-то не работает.

Решение

Найдено Как выполнить программную аутентификацию с помощью Dex? #140. Изменив код в соответствии с предоставленным там решением, он сработал.

Сначала необходимо выполнить шаги , описанные в разделе « Подключение к конвейерам Kubeflow из-за пределов кластера» , чтобы иметь возможность подключаться через localhost:3000.

      import requests
import kfp
import kfp.dsl as dsl
from kfp.components import create_component_from_func


# Does not work
#import kfp
#client = kfp.Client(host='http://localhost:3000', namespace='kubeflow')
#print(client.list_experiments(namespace='kubeflow'))


# --------------------------------------------------------------------------------

# How to do programmatic authentication with Dex? #140
# --------------------------------------------------------------------------------
HOST = "http://localhost:8080/"
USERNAME = "user@example.com"
PASSWORD = "12341234"
NAMESPACE = "kubeflow-user-example-com"

session = requests.Session()
response = session.get(HOST)

headers = {
    "Content-Type": "application/x-www-form-urlencoded",
}

data = {"login": USERNAME, "password": PASSWORD}
session.post(response.url, headers=headers, data=data)
session_cookie = session.cookies.get_dict()["authservice_session"]

client = kfp.Client(
    host=f"{HOST}/pipeline",
    cookies=f"authservice_session={session_cookie}",
    namespace=NAMESPACE,
)

print(client.list_pipelines())


def add(a: float, b: float) -> float:
    '''Calculates sum of two arguments'''
    return a + b


add_op = create_component_from_func(
    add, output_component_file='add_component.yaml')


@dsl.pipeline(
    name='Addition pipeline',
    description='An example pipeline that performs addition calculations.'
)
def add_pipeline(
        a='1',
        b='7',
):
    # Passes a pipeline parameter and a constant value to the `add_op` factory
    # function.
    first_add_task = add_op(a, 4)
    # Passes an output reference from `first_add_task` and a pipeline parameter
    # to the `add_op` factory function. For operations with a single return
    # value, the output reference can be accessed as `task.output` or
    # `task.outputs['output_name']`.
    second_add_task = add_op(first_add_task.output, b)

# Specify argument values for your pipeline run.
arguments = {'a': '7', 'b': '8'}

# Create a pipeline run, using the client you initialized in a prior step.
#client.create_run_from_pipeline_func(add_pipeline, arguments=arguments)

kfp.compiler.Compiler().compile(
    pipeline_func=add_pipeline,
    package_path='pipeline.yaml')

По-видимому, реализация многопользовательской изоляции вызвала проблемы, и похоже, что документация в Pipelines SDK не была обновлена.

Получил отзыв от разработчиков (см. Закрытый вопрос ). Это одно из текущих предупреждений о многопользовательском режиме (см. Документацию ). Это использование теперь поддерживается через #5138 .
