How to use the pydocstyle.utils.log.setLevel function in pydocstyle

def test_flake8():
    # for some reason the pydocstyle logger changes to an effective level of 1
    # set higher level to prevent the output to be flooded with debug messages
    log.setLevel(logging.WARNING)

    style_guide = get_style_guide(
        extend_ignore=['D100', 'D104'],
        show_source=True,
    )
    style_guide_tests = get_style_guide(
        extend_ignore=['D100', 'D101', 'D102', 'D103', 'D104', 'D105', 'D107'],
        show_source=True,
    )

    stdout = sys.stdout
    sys.stdout = sys.stderr
    # implicitly calls report_errors()
    report = style_guide.check_files([
        str(Path(__file__).parents[1] / 'bin' / 'colcon'),
        str(Path(__file__).parents[1] / 'colcon_core'),
