airflow - 如何抑制气流 cli 输出中的错误？

问题描述

研究一些气流监控的想法。当我执行时，airflow list_tasks my_dag我会得到很多不需要的垃圾以及实际所需的输出：

[2018-12-11 22:39:00,301] {__init__.py:51} INFO - Using executor SequentialExecutor

SyntaxError: invalid syntax
also_run_this
run_after_loop
run_this_last
runme_0
runme_1
runme_2

我真正需要的是：

还有_run_this

run_after_loop

run_this_last

runme_0

runme_1

runme_2

除了实际结果之外，有没有办法压制所有？

解决方案

将坚韧升级到最新版本。虽然在升级过程中它会显示一个警告：“apache-airflow 1.10.1 有要求 tenacity==4.8.0，但你将有不兼容的韧度 5.0.2”。请忽略这个

兼容性：Python 3.7.1 apache-airflow 1.10.1 韧性 5.0.2

希望这可以帮助！
