Hi Mark,
Thank you for the issue. That seems like an interactive Python session. I think you may have accidentally called basic_config, then get_logger, then basic_config again. The following code works for me without any errors:

import logwood
from logwood.handlers.stderr import ColoredStderrHandler
logwood.basic_config(
    level = logwood.INFO,
    handlers = [ColoredStderrHandler()]
)
logger = logwood.get_logger('LoggerName')
from aiodebug import log_slow_callbacks
log_slow_callbacks.enable(0.05)

For example, with a fresh environment and latest package versions:

$ mkvirtualenv tmp
created virtual environment CPython3.8.2.final.0-64 in 384ms
...

$ pip install logwood aiodebug
...
Successfully installed aiodebug-1.1.2 logwood-3.1.0

$ python test.py
$

Hope this helps,
Vita
