auto-sklearn modifies logging.basicConfig

[koreyou]

It seems that autosklearn uses logging.basicConfig internally, which may overwrite library users' logging setting in undesired way.
(it took me some time to figure out what was suddenly breaking my logging setting)
Shouldn't it change the setting of local logger instead of changing the global setting?

Code to reproduce:

import logging
import autosklearn.classification

logging.basicConfig(level=logging.INFO)
# it will output "<Logger test (WARNING)>"
print(logging.getLogger("test"))

In the mean time, there is a easy workaround:

import logging
logging.basicConfig(level=logging.INFO)
import autosklearn.classification

# it will output "<Logger test (INFO)>"
print(logging.getLogger("test"))

This should be fixed by #505. Please reopen if this problem still exists.

@mfeurer How does #505 fixes the issue?
Logging should not be all messed up after import... Is there a way to simply disable logging from auto-sklearn?

[mfeurer]

You can pass a dictionary with logging configuration to change the behavior of the logger in Auto-sklearn.

This worked to disable the annoying py4j.java_gateway INFO msgs:

# https://docs.python.org/3/library/logging.config.html
# https://docs.python.org/3/howto/logging-cookbook.html
import logging.config

# https://github.com/automl/auto-sklearn/blob/master/autosklearn/util/logging.yaml
config = {
  "version": 1,
  "incremental": True,
  "loggers": {
    "py4j.java_gateway": {"level": "WARNING"}
  }
}

logging.config.dictConfig(config)

I have a logging question about autosklearn, would really appreciate if someone could guide me: https://stackoverflow.com/questions/73310967/how-can-i-use-auto-sklearn-without-affecting-my-root-logger

Hi @sergeiissaev,

I would always recommend asking questions here over stack overflow if you want direct answers from us :)

Take a look at this example:

Best,
