In most callbacks, when logging information, print is used. But the standard logging library is also used for warning or error. Why logging.info is not used instead of print ?
For example, in the ReduceLROnPlateau callback, on_epoch_end, it is the following :
print('\nEpoch %05d: ReduceLROnPlateau reducing learning rate to %s.' % (epoch + 1, new_lr))
But for the warning, the standard logging library is used :
logging.warning('Learning rate reduction mode %s is unknown, fallback to auto mode.', self.mode)
I’m currently trying to redirected the print to a logger and it would have been much simpler if logging.info was used. Any ideas on why this is done like this and if I should bother to make a PR to change that ?
