importing swifter hijacks logging

If I am logging to console or file, just the act of importing swifter stops all logging.

I have tested this in a fresh colab with only swifter installed, and it is also the case with logging.handlers.RotatingFileHandler

MWE:

import logging
import pandas as pd

logger = logging.getLogger('myapp')
logger.setLevel(logging.DEBUG)
handler = logging.StreamHandler()
formatter = '[%(levelname)s] - %(asctime)s : %(message)s'
handler.setFormatter(logging.Formatter(formatter))
logger.addHandler(handler)
logger.debug('message')

[DEBUG] - 2020-10-22 23:00:12,202 : message

pip install -q swifter
import swifter
logger.debug('message after importing swifter')

[no output]

Hi @gkennos , thanks for raising this!

This is definitely concerning. Let me look into resolving this. The original purpose of disabling logging for swifter was to avoid repeated logging during swifter’s applies. See #130 for a discussion. I’ll follow-up here when I have a solution.

Thanks, Jason
