Use Logger

This document is used to introduce how to use a unified Logger in LibCity to output necessary auxiliary information. The logger that can show a message on standard output and write it into the file simultaneously.

First call utils.utils.get_logger() in the entry file test_model.py to instantiate the Logger object.

from libcity.utils import get_logger
logger = get_logger(config)

You can use Logger in the file you want like this:

from logging import getLogger
from libcity.model.abstract_model import AbstractModel

class NewModel(AbstractModel):
    def __init__(self, config, data_feature):
        self._logger = getLogger()
        
    def forward(self, batch):
        self._logger.info("hahhh")
