Consider the following example:
from loguru import logger
import sys
logger.add(sys.stdout, level="INFO")
It is pretty simple to create a hydra config for the level parameter:
log:
level: INFO
On the other hand, I don't know how to create a config parameter for sys.stdout? I tried to do something like:
log:
level: INFO
stream: sys.stdout
However, in the script:
@hydra.main(version_base=None, config_path="../config", config_name="main")
set_log(cfg: DictConfig):
logger.add(cfg.log.stream, level=cfg.log.level)
cfg.log.stream gives the string "sys.stdout". How to solve it?
Maybe not the most elegant solution, but the shortest one is the resort to eval()
@hydra.main(version_base=None, config_path="../config", config_name="main")
set_log(cfg: DictConfig):
logger.add(eval(cfg.log.stream), level=cfg.log.level)
