pip install apache-airflow[taskflow] 导入正确的模块 确保您导入了正确的Taskflow API模块。例如: 代码语言:javascript 复制 from airflow.decoratorsimportdag,task from airflow.utils.datesimportdays_ago 正确使用装饰器 使用@dag和@task装饰器定义DAG和任务
有没有办法让第二个 dag 检索第一个 dag 的 push_data 任务返回的值? (现在我收到的是 '{{ task_instance.xcom_pull(task_ids='push_data', dag_id='xcom_test_start', key='return_value') }}') uiflow_xcom_test_dataset = Dataset("uiflow_xcom_test") @dag( dag_id="xcom_test_start...
使用TaskFlow API 有多种方法可以实现此目的: import datetime from airflow.decorators import dag, task from airflow.operators.python import get_current_context @dag(start_date=datetime.datetime(2023, 1, 1), schedule=None) def so_75303816(): @task def example_1(**context): foo = context["dag...
In this course, Build DAGs Using the Taskflow API in Apache Airflow, you’ll gain the ability to create directed acyclic graphs (DAGs) for streamlined data validation, filtering, and passing. First, you’ll set up a simple DAG, with no conditional operations, using Airflow operators for ...

而不是您将其作为Kwarg参数传递给它。因此,类似的事情应该有效: Variable.get('knmi_api_key', deserialize_json=True)['api_key'] UPD:在气流2.8中更改:以前上下文密钥参数必须提供默认值,例如var =无。这不再需要。 python jinja2 airflow 最新问题
