How can I find the artifacts logged or consumed by a run? How can I find the runs that produced or consumed an artifact?

This page shows you how to trace the relationships between runs and artifacts in W&B. You can find which run produced or consumed a given artifact, or which artifacts a given run produced or consumed. This is useful for auditing data lineage, debugging pipelines, and understanding how artifacts flow through your experiments.

W&B tracks the artifacts that each run logs and uses to construct an artifact graph. This graph is a bipartite, directed, acyclic graph with nodes that represent runs and artifacts. See an example artifact graph and click Explode to expand the graph.

Use the W&B Public API to navigate the graph programmatically, starting from either an artifact or a run. Choose the tab that matches your starting point.

From an artifact

api = wandb.Api()

artifact = api.artifact("[PROJECT]/[ARTIFACT]:[ALIAS]")

# Walk up the graph from an artifact:
producer_run = artifact.logged_by()
# Walk down the graph from an artifact:
consumer_runs = artifact.used_by()

# Walk down the graph from a run:
next_artifacts = consumer_runs[0].logged_artifacts()
# Walk up the graph from a run:
previous_artifacts = producer_run.used_artifacts()

From a run

api = wandb.Api()

run = api.run("[ENTITY]/[PROJECT]/[RUN_ID]")

# Walk down the graph from a run:
produced_artifacts = run.logged_artifacts()
# Walk up the graph from a run:
consumed_artifacts = run.used_artifacts()

# Walk up the graph from an artifact:
earlier_run = consumed_artifacts[0].logged_by()
# Walk down the graph from an artifact:
consumer_runs = produced_artifacts[0].used_by()
