Use lineage graphs to visualize a linked artifact’s history and audit a collection’s history.

Use a lineage graph to visualize a linked artifact’s history. Audit a collection’s history to track changes made to artifacts in that collection.

Lineage graphs#

Within a collection in the W&B Registry, you can view a history of the artifacts that an ML experiment uses. This history is called a lineage graph.

A lineage graph shows:

• Artifacts used as inputs to a run.
• Artifacts created as outputs from a run.

In other words, a lineage graph shows the input and output of a run.

For example, the following image shows a typical lineage graph for artifacts created and used throughout an ML experiment:

From left to right, the image shows:

1. Multiple runs log the split_zoo_dataset:v4 artifact.
2. The “rural-feather-20” run uses the split_zoo_dataset:v4 artifact for training.
3. The output of the “rural-feather-20” run is a model artifact called zoo-ylbchv20:v0.
4. A run called “northern-lake-21” uses the model artifact zoo-ylbchv20:v0 to evaluate the model.

To view a lineage graph for an artifact in a collection:

1. Navigate to the W&B Registry.
2. Select the collection that contains the artifact.
3. From the dropdown, select the artifact version you want to view its lineage graph.
4. Select the Lineage tab.
5. Select a node to view detailed information about the run or artifact.

See Enable lineage graph tracking to learn how to track the input and output of a run using the W&B Python SDK.

The following image shows the expanded detailed view of a run (rural-feather-20) when you select a node in the lineage graph:

The following image shows the expanded detailed view of an artifact (zoo-ylbchv20:v0) when you select an artifact node in the lineage graph:

You can also view lineage graphs for artifacts you log to W&B that are not part of a collection. See Explore artifact graphs for more information.

Audit a collection’s history#

View actions that members of your organization take on that collection. You can view:

• If an alias was added or removed from an artifact version.
• If an artifact version was added or removed from a collection.

For both actions, you can view the user that performed the action and the date the action occurred.

To view a collection’s action history:

1. Navigate to the W&B Registry.
2. Select the collection you want to view its action history.
3. Select the dropdown menu next to the collection name.
4. Select the Action History option.
