Methods

method Api.artifact()

Returns a single artifact.
Arguments
  • name: The artifact’s name. The name of an artifact resembles a filepath that consists, at a minimum, the name of the project the artifact was logged to, the name of the artifact, and the artifact’s version or alias. Optionally append the entity that logged the artifact as a prefix followed by a forward slash. If no entity is specified in the name, the Run or API setting’s entity is used.
  • type: The type of artifact to fetch.
Raises
  • ValueError: If the artifact name is not specified.
  • ValueError: If the artifact type is specified but does not match the type of the fetched artifact.
Examples
In the following code snippets “entity”, “project”, “artifact”, “version”, and “alias” are placeholders for your W&B entity, name of the project the artifact is in, the name of the artifact, and artifact’s version, respectively.

method Api.artifact_collection()

Returns a single artifact collection by type. You can use the returned ArtifactCollection object to retrieve information about specific artifacts in that collection, and more.
Arguments
  • type_name: The type of artifact collection to fetch.

method Api.artifact_collection_exists()

Whether an artifact collection exists within a specified project and entity.
Arguments
  • name: An artifact collection name. Optionally append the entity that logged the artifact as a prefix followed by a forward slash. If entity or project is not specified, infer the collection from the override params if they exist. Otherwise, entity is pulled from the user settings and project will default to “uncategorized”.
  • type: The type of artifact collection.
Examples
In the proceeding code snippet “type”, and “collection_name” refer to the type of the artifact collection and the name of the collection, respectively.

method Api.artifact_exists()

Whether an artifact version exists within the specified project and entity.
Arguments
  • name: The name of artifact. Add the artifact’s entity and project as a prefix. Append the version or the alias of the artifact with a colon.

  • filters: (dict) queries for specific runs using the MongoDB query language. You can filter by run properties such as config.key, summary_metrics.key, state, entity, createdAt, etc. For example: {"config.experiment_name": "foo"} would find runs with a config entry of experiment name set to “foo”
  • order: (str) Order can be created_at, heartbeat_at, config.*.value, or summary_metrics.*. If you prepend order with a + order is ascending (default). If you prepend order with a - order is descending. The default order is run.created_at from oldest to newest.
  • per_page: (int) Sets the page size for query pagination.
  • include_sweeps: (bool) Whether to eagerly fetch the sweep object in each run result.
  • lazy: (bool) Whether to use lazy loading for faster performance. When True (default), only essential run metadata is loaded initially. Heavy fields like config, summaryMetrics, and systemMetrics are loaded on-demand when accessed. Set to False for full data upfront.
