Settings

Settings for the W&B SDK.

This class manages configuration settings for the W&B SDK, ensuring type safety and validation of all settings. Settings are accessible as attributes and can be initialized programmatically, through environment variables (WANDB_ prefix), and with configuration files.

The settings are organized into three categories:

1. Public settings: Core configuration options that users can safely modify to customize W&B’s behavior for their specific needs.
2. Internal settings: Settings prefixed with ‘x_’ that handle low-level SDK behavior. These settings are primarily for internal use and debugging. While they can be modified, they are not considered part of the public API and may change without notice in future versions.
3. Computed settings: Read-only settings that are automatically derived from other settings or the environment.

Attributes:

• allow_offline_artifacts (bool): Flag to allow table artifacts to be synced in offline mode. To revert to the old behavior, set this to False.

• allow_val_change (bool): Flag to allow modification of Config values after they’ve been set.

• anonymous (Optional): Controls anonymous data logging. Possible values are:

  • “never”: requires you to link your W&B account before tracking the run, so you don’t accidentally create an anonymous run.
  • “allow”: lets a logged-in user track runs with their account, but lets someone who is running the script without a W&B account see the charts in the UI.
  • “must”: sends the run to an anonymous account instead of to a signed-up user account.

• api_key (Optional): The W&B API key.

• azure_account_url_to_access_key (Optional): Mapping of Azure account URLs to their corresponding access keys for Azure integration.

• base_url (str): The URL of the W&B backend for data synchronization.

• code_dir (Optional): Directory containing the code to be tracked by W&B.

• config_paths (Optional): Paths to files to load configuration from into the Config object.

• console (Literal): The type of console capture to be applied. Possible values are: “auto” - Automatically selects the console capture method based on the system environment and settings. “off” - Disables console capture. “redirect” - Redirects low-level file descriptors for capturing output. “wrap” - Overrides the write methods of sys.stdout/sys.stderr. Will be mapped to either “wrap_raw” or “wrap_emu” based on the state of the system. “wrap_raw” - Same as “wrap” but captures raw output directly instead of through an emulator. Derived from the wrap setting and should not be set manually. “wrap_emu” - Same as “wrap” but captures output through an emulator. Derived from the wrap setting and should not be set manually.

• console_multipart (bool): Whether to produce multipart console log files.

• credentials_file (str): Path to file for writing temporary access tokens.

• disable_code (bool): Whether to disable capturing the code.

• disable_git (bool): Whether to disable capturing the git state.

• disable_job_creation (bool): Whether to disable the creation of a job artifact for W&B Launch.

• docker (Optional): The Docker image used to execute the script.

• email (Optional): The email address of the user.

• entity (Optional): The W&B entity, such as a user or a team.

• force (bool): Whether to pass the force flag to wandb.login().

• fork_from (Optional): Specifies a point in a previous execution of a run to fork from. The point is defined by the run ID, a metric, and its value. Currently, only the metric ‘_step’ is supported.

• git_commit (Optional): The git commit hash to associate with the run.

• git_remote (str): The git remote to associate with the run.

• git_remote_url (Optional): The URL of the git remote repository.

• git_root (Optional): Root directory of the git repository.

• host (Optional): Hostname of the machine running the script.

• http_proxy (Optional): Custom proxy servers for http requests to W&B.

• https_proxy (Optional): Custom proxy servers for https requests to W&B.

• identity_token_file (Optional): Path to file containing an identity token (JWT) for authentication.

• ignore_globs (Sequence): Unix glob patterns relative to files_dir specifying files to exclude from upload.

• init_timeout (float): Time in seconds to wait for the wandb.init call to complete before timing out.

• insecure_disable_ssl (bool): Whether to insecurely disable SSL verification.

• job_name (Optional): Name of the Launch job running the script.

• job_source (Optional): Source type for Launch.

• label_disable (bool): Whether to disable automatic labeling features.

• launch_config_path (Optional): Path to the launch configuration file.

• login_timeout (Optional): Time in seconds to wait for login operations before timing out.

• mode (Literal): The operating mode for W&B logging and synchronization.

• notebook_name (Optional): Name of the notebook if running in a Jupyter-like environment.

• organization (Optional): The W&B organization.

• program (Optional): Path to the script that created the run, if available.

• program_abspath (Optional): The absolute path from the root repository directory to the script that created the run. Root repository directory is defined as the directory containing the .git directory, if it exists. Otherwise, it’s the current working directory.

• program_relpath (Optional): The relative path to the script that created the run.

• project (Optional): The W&B project ID.

• quiet (bool): Flag to suppress non-essential output.

• reinit (Union): What to do when wandb.init() is called while a run is active. Options:

  • “default”: Use “finish_previous” in notebooks and “return_previous” otherwise.
  • “return_previous”: Return the most recently created run that is not yet finished. This does not update wandb.run; see the “create_new” option.
  • “finish_previous”: Finish all active runs, then return a new run.
  • “create_new”: Create a new run without modifying other active runs. Does not update wandb.run and top-level functions like wandb.log. Because of this, some older integrations that rely on the global run will not work. Can also be a boolean, but this is deprecated. False is the same as “return_previous”, and True is the same as “finish_previous”.

• relogin (bool): Flag to force a new login attempt.

• resume (Optional): Specifies the resume behavior for the run. Options:

  • “must”: Resumes from an existing run with the same ID. If no such run exists, it will result in failure.
  • “allow”: Attempts to resume from an existing run with the same ID. If none is found, a new run will be created.
  • “never”: Always starts a new run. If a run with the same ID already exists, it will result in failure.
  • “auto”: Automatically resumes from the most recent failed run on the same machine.

• resume_from (Optional): Specifies a point in a previous execution of a run to resume from. The point is defined by the run ID, a metric, and its value. Currently, only the metric ‘_step’ is supported.

• root_dir (str): The root directory to use as the base for all run-related paths. In particular, this is used to derive the wandb directory and the run directory.

• run_group (Optional): Group identifier for related runs. Used for grouping runs in the UI.

• run_id (Optional): The ID of the run.

• run_job_type (Optional): Type of job being run (e.g., training, evaluation).

• run_name (Optional): Human-readable name for the run.

• run_notes (Optional): Additional notes or description for the run.

• run_tags (Optional): Tags to associate with the run for organization and filtering.

• sagemaker_disable (bool): Flag to disable SageMaker-specific functionality.

• save_code (Optional): Whether to save the code associated with the run.

• settings_system (Optional): Path to the system-wide settings file.

• show_errors (bool): Whether to display error messages.

• show_info (bool): Whether to display informational messages.

• show_warnings (bool): Whether to display warning messages.

• silent (bool): Flag to suppress all output.

• strict (Optional): Whether to enable strict mode for validation and error checking.

• summary_timeout (int): Time in seconds to wait for summary operations before timing out.

• sweep_id (Optional): Identifier of the sweep this run belongs to.

• sweep_param_path (Optional): Path to the sweep parameters configuration.

• symlink (bool): Whether to use symlinks (True by default except on Windows).

• sync_tensorboard (Optional): Whether to synchronize TensorBoard logs with W&B.

• table_raise_on_max_row_limit_exceeded (bool): Whether to raise an exception when table row limits are exceeded.

• username (Optional): Username.

• x_skip_transaction_log (bool): Whether to skip saving the run events to the transaction log. This is only relevant for online runs. Can be used to reduce the amount of data written to disk. Should be used with caution, as it removes the gurantees about recoverability.

• x_stats_open_metrics_endpoints (Optional): OpenMetrics /metrics endpoints to monitor for system metrics.

• x_stats_open_metrics_filters (Union): Filter to apply to metrics collected from OpenMetrics /metrics endpoints. Supports two formats:

  • {“metric regex pattern, including endpoint name as prefix”: {“label”: “label value regex pattern”}}
  • (“metric regex pattern 1”, “metric regex pattern 2”, …)
