Does logging block my training?
No, wandb.log writes to a local file and a separate process syncs data asynchronously.
How can I overwrite the logs from previous steps?
Use forking and rewind to overwrite logs from previous steps in a W&B run.
How do I log a list of values?
Log a list of values using wandb.log with dictionaries or wandb.Table for structured data.
How do I log runs launched by continuous integration or internal tools?
Use a service account API key for CI and automated jobs, and set WANDB_USERNAME to attribute runs.
How do I log to the right wandb user on a shared machine?
Set the WANDB_API_KEY environment variable to authenticate as the correct user on shared machines.
How do I turn off logging?
Run wandb offline to set WANDB_MODE=offline and stop syncing data to the W&B server.
Which files should I check when my code crashes?
Check debug.log and debug-internal.log in the wandb run directory to diagnose crashes.
