After call NeighborLoader my file logger prints in console

🐛 Describe the bug

After call bellow, my file logger outputs to console, and changed the log format. Except that all fine. Could you tell me it is bug or i did wrong?

Versions

train_loader = NeighborLoader(
                                dataset._data,
                                num_neighbors = {key: NEIGHBOR_SIZES for key in dataset._data.edge_types},
                                batch_size=BATCH_SIZE,
                                input_nodes=('user', train_mask)
                                )

My logger:

def get_file_pylogger(filepath: str, name: str = __name__) -> logging.Logger:
    """Initialize .log file logger"""
    formatter = logging.Formatter(
        fmt="%(asctime)s %(levelname)s %(message)s",
        datefmt="%Y-%m-%d %H:%M:%S",
    )
    logger = logging.getLogger(name)
    file_handler = logging.FileHandler(filepath, "a+")
    file_handler.setFormatter(formatter)
    logger.addHandler(file_handler)
    logger.setLevel(logging.DEBUG)
    return logger

I'm not sure if I correctly understand what issue you're experiencing. Can you elaborate more? What's the expected behaviour? Can you share a minimal script and env details that reproduces the misbehaviour you're referring to?

I am using two types of loaders. if sampler is not 'neighbor', log.info outputs to file. if sampler is 'neighbor', log.info outputs file and console. I thoughts it is NeighborLoader's bug related with standard output. Maybe i did wrong with log.

file_log = util.get_file_pylogger(os.path.join(path,'run_logs', logfilename), 'filelogger')
log.handlers.append(file_log.handlers[0])
...
if SAMPLER == 'neighbor':
      train_loader = NeighborLoader(
          dataset._data,
          num_neighbors = {key: NEIGHBOR_SIZES for key in dataset._data.edge_types},
          batch_size=BATCH_SIZE,
          input_nodes=('user', train_mask)
          )
else:
      train_loader = DataLoader(dataset, batch_size=BATCH_SIZE)
...
log.info('result')

Mind sharing minimal code I can run for reproduction?
