How to Change the Loglevel or Silence All Logs for a Third Party Library in Python?
问题
以下是您要求的代码部分的翻译：
这是我的代码的外观。
#!/usr/bin/env python3
# encoding:utf-8
import logging, asyncua
logging.basicConfig(format='%(asctime)s | %(levelname)s: %(message)s',
level=logging.INFO)
...# 其他内容
logging.info(msg='我的消息')
但似乎asyncua库内部有一个非常冗长的日志设置，即使在info级别也是如此。因此，当我将我的日志级别设置为info或debug时，该库会在控制台中填充不必要的（至少对我来说是不必要的）消息，导致我的自定义日志消息丢失。我正在使用的解决方法是将自己的日志级别设置为ERROR，以抑制其info/debug日志，并将所有我的消息记录为错误，这似乎是一种可怕的解决方法，以避免这种情况。
那么，如何完全消除来自我的导入的任何日志，或将它们都设置为error/warning级别，以确保我的自定义日志不会在控制台中丢失？是否有一种方法可以覆盖所有相关库，不仅仅是asyncua，还包括例如tensorflow？
英文:
Here is how my code looks like.
#!/usr/bin/env python3
# encoding:utf-8
import logging, asyncua
logging.basicConfig(format='%(asctime)s | %(levelname)s: %(message)s',
level=logging.INFO)
...# Other stuffs
logging.info(msg='My message')
But seems like the asyncua library has an extremely verbose log setting inside, even at info level. So as I set my loglevel to info or debug, the library itself fills my console with unnecessary (at least to me) messages where my own log messages get lost. The workaround I am using is setting my own loglevel as ERROR to suppress their info/debug log and logging all my messages as error, which seem like a terrible hack to avoid.
So how do I totally silence any log from my imports, or set them all at error/warning level, to make sure my own logs do not get lost in the console? Is there a method that covers all relevant libraries, not just asyncua, but also, for example, tensorflow?

得分: 1
查找第三方库的文档或源代码，找出顶级日志记录器的名称（例如可能是asyncua、tensorflow），然后根据需要设置这些记录器的级别，例如：
logging.getLogger('asyncua').setLevel(logging.ERROR)
使用级别logging.CRITICAL + 1来完全禁止它们的日志输出（假设它们只使用标准的日志级别）。
英文:
Find out the names of the top-level loggers for your third-party libraries from their documentation or source code (e.g. might be asyncua, tensorflow) and then set the level of those loggers to suit your need, e.g.
logging.getLogger('asyncua').setLevel(logging.ERROR)
and use level logging.CRITICAL + 1 to completely silence them (assuming they just use the standard logging levels).
