Why install av twice?

[zhongqiu1245]

Hello dear authors!
Thank you for your amazing job!
In mmagic/requirements/runtime.txt, I find mmagic installs av twice:

av
av==8.0.3; python_version < '3.7'

Could you tell me why mmagic installs av twice?
And the python_version must be lower than 3.7? Because other mm-products require python>=3.8. It will have negative effect for mmagic if I install mmagic in python>=3.8?
Thank you !

this mean we install av==8.0.3 when python_version < '3.7'. MMagic can be used on python>=3.8 .
