How do I silence W&B info messages?

W&B emits info-level log messages by default, which can clutter notebook output. This page describes two ways to reduce or silence those messages: adjust the Python logger level, or use a W&B environment variable.

To suppress log messages in your notebook such as this:

INFO SenderThread:11484 [sender.py:finish():979]

Set the log level to logging.ERROR to show only errors, which suppresses info-level log output.

import logging

logger = logging.getLogger("wandb")
logger.setLevel(logging.ERROR)

Alternatively, use a W&B environment variable to control log verbosity:

• To reduce log output, set the WANDB_QUIET environment variable to True.
• To turn off log output completely, set the WANDB_SILENT environment variable to True.

In a notebook, set WANDB_QUIET or WANDB_SILENT before you run wandb.login:

Notebook

%env WANDB_SILENT=True

Python

import os

os.environ["WANDB_SILENT"] = "True"
