how to turn off INFO messages when run in command-line mode

I am running allennlp in command-line mode. Is there any way to turn off INFO messages ? From an earlier issue I see that there is an environment variable that can be set. I am not sure what to set it to.

if os.environ.get("ALLENNLP_DEBUG"): LEVEL = logging.DEBUG else: LEVEL = logging.INFO

doing an "export ALLENNLP_DEBUG=DEBUG" in a bash shell doesn't seem to suppress INFO messages.
