Howto configure logging,let it support to write logs to a file? about abseil-py HOT 5 CLOSED

How about running with the --alsologtostderr flag?

from abseil-py.

You can get it working by specifying --log_dir=<log directory> on the commandline and adding to the beginning of your program something like:

import os

from absl import flags
from absl import logging

FLAGS = flags.FLAGS

...

if FLAGS.log_dir:
    if not os.path.exists(FLAGS.log_dir):
        os.makedirs(FLAGS.log_dir)
    logging.get_absl_handler().use_absl_log_file('2018_12_02_absl_logging', FLAGS.log_dir)

from abseil-py.

use_absl_log_file by default checks FLAGS.log_dir, so you can just do:

from absl import app
from absl import logging

def main(argv):
    if len(argv) > 1:
        raise app.UsageError('Too many command-line arguments.')
    logging.get_absl_handler().use_absl_log_file()

if __name__ == '__main__':
    app.run(main)
