Create, update, or manage a hyperparameter sweep. Provide a YAML config file to create a sweep. Define the search strategy, parameters, and metric to optimize in the config. Register the sweep with the W&B server and print the sweep ID and a command to start an agent. Provide a sweep ID (or full path entity/project/sweep_id) with a state flag (--stop, --cancel, --pause, or --resume) to manage an existing sweep. The sweep ID is a unique identifier for the sweep, generated by W&B when the sweep is created. You can find the sweep ID in the W&B App or in the output of the wandb sweep command when you create a new sweep. For example, to create a sweep using the configuration defined in sweep_config.yaml. Use the current user’s default entity and project:
$ wandb sweep sweep_config.yaml
To create a sweep and store the results under the “team-awesome” entity and “foobar” project:
$ wandb sweep -p foobar -e team-awesome sweep_config.yaml
To update sweep abcd1234 with a new configuration from sweep_config.yaml. This is useful for changing the parameters or search strategy of an active sweep:
$ wandb sweep --update abcd1234 sweep_config.yaml
To stop sweep abcd1234 under the “team-awesome” entity and “foobar” project:
$ wandb sweep --stop team-awesome/foobar/abcd1234
To cancel sweep abcd1234 in the current user’s default entity and project:
$ wandb sweep --cancel abcd1234
To pause sweep abcd1234 in the current user’s default entity and project. Later, resume the sweep:
$ wandb sweep --pause abcd1234
$ wandb sweep --resume abcd1234
To create a sweep with a local controller that uses the configuration in sweep_config.yaml:
$ wandb sweep --controller sweep_config.yaml
To create a new sweep and include two previously completed runs (run ID abcd1234 and run ID efgh5678) so their results are incorporated into the sweep’s hyperparameter search:
$ wandb sweep -R abcd1234 -R efgh5678 sweep_config.yaml
