What happens if internet connection is lost while I'm training a model?

Learn how W&B retries syncing on connection loss and how to use offline mode for training.

If the library cannot connect to the internet, it enters a retry loop and continues to attempt to stream metrics until the network is restored. The program continues to run during this time.

To run on a machine without internet, set WANDB_MODE=offline. This configuration stores metrics locally on the hard drive. Later, call wandb sync DIRECTORY to stream the data to the server.
