如何抑制气流cli输出中的误差？

Question

研究一些气流监测的想法。当我执行时，airflow list_tasks my_dag我得到了大量不必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：

Also_run_this

run_after_loop

run_this_last

runme_0

runme_1

runme_2

除了实际结果，有没有办法抑制所有这些？

将韧度升级到最新版本尽管在升级时，它显示警告：“ apache-airflow 1.10.1要求韧度== 4.8.0，但您将具有不相容的韧度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！
