##问题分析大致意思是：弃用警告：从collections中导入ABCs已被弃用，并在python3.8中将停止工作，可使用collections.abc代替它进行使用然后就各种百度了解，主要看到两种解决办法，做一下简单汇总：第一种： 在代码文件中用到了 collections 这个模块的报错；第二种：在代码文件中没有用到 collections 这个模块的报错；##解决方法

1. 如果有使用这个方法

# from collections import Iterable   ---这是会报警告的用法from collections.abc import Iterable ---这是不会报警告的用法

1. 如果根本没用调用这个方法那么只能通过pytest的告警过滤了创建pytest.ini文件，写入下面内容并保存

[pytest]addopts = -p no:warnings

运行后，告警消除
