The W&B API is rate limited by IP and API key. New accounts are restricted to 200 requests per minute. This rate allows you to run approximately 15 processes in parallel and have them report without being throttled. If the wandb client detects it's being limited, it will backoff and retry sending the data in the future. If you need to run more than 15 processes in parallel send an email to firstname.lastname@example.org.
The maximum file size for new accounts is 500MB. A single run is allowed to store 1GB of data. If you need to store larger files or more data per run, contact us at email@example.com.
Metrics are sampled to 500 data points before displaying in the UI. Generally you shouldn't be calling
wandb.log more than 10,000 times in a single training run. If the amount of metrics being sent to us exceeds 10MB we will begin dropping future data points.
While a run is in progress we tail the last 5000 lines of your log for you in the UI. After a run is completed the entire log is archived and can be downloaded from an individual run page.
