Wallaroo SDK Tag Management

Tags are applied to either model versions or pipelines. This allows organizations to track different versions of models, and search for what pipelines have been used for specific purposes such as testing versus production use.

Create Tag

Tags are created with the Wallaroo client command create_tag(String tagname). This creates the tag and makes it available for use.

The tag will be saved to the variable currentTag to be used in the rest of these examples.

# Now we create our tag
currentTag = wl.create_tag("My Great Tag")

List Tags

Tags are listed with the Wallaroo client command list_tags(), which shows all tags and what models and pipelines they have been assigned to.

# List all tags

wl.list_tags()

Wallaroo Pipeline Tag Management

Tags are used with pipelines to track different pipelines that are built or deployed with different features or functions.

Add Tag to Pipeline

Tags are added to a pipeline through the Wallaroo Tag add_to_pipeline(pipeline_id) method, where pipeline_id is the pipeline’s integer id.

For this example, we will add currentTag to testtest_pipeline, then verify it has been added through the list_tags command and list_pipelines command.

# add this tag to the pipeline
currentTag.add_to_pipeline(tagtest_pipeline.id())

{'pipeline_pk_id': 1, 'tag_pk_id': 1}

Search Pipelines by Tag

Pipelines can be searched through the Wallaroo Client search_pipelines(search_term) method, where search_term is a string value for tags assigned to the pipelines.

In this example, the text “My Great Tag” that corresponds to currentTag will be searched for and displayed.

wl.search_pipelines('My Great Tag')

Remove Tag from Pipeline

Tags are removed from a pipeline with the Wallaroo Tag remove_from_pipeline(pipeline_id) command, where pipeline_id is the integer value of the pipeline’s id.

For this example, currentTag will be removed from tagtest_pipeline. This will be verified through the list_tags and search_pipelines command.

## remove from pipeline
currentTag.remove_from_pipeline(tagtest_pipeline.id())

{'pipeline_pk_id': 1, 'tag_pk_id': 1}

Wallaroo Model Tag Management

Tags are used with models to track differences in model versions.

Assign Tag to a Model

Tags are assigned to a model through the Wallaroo Tag add_to_model(model_id) command, where model_id is the model’s numerical ID number. The tag is applied to the most current version of the model.

For this example, the currentTag will be applied to the tagtest_model. All tags will then be listed to show it has been assigned to this model.

# add tag to model

currentTag.add_to_model(tagtest_model.id())

{'model_id': 1, 'tag_id': 1}

Search Models by Tag

Model versions can be searched via tags using the Wallaroo Client method search_models(search_term), where search_term is a string value. All models versions containing the tag will be displayed. In this example, we will be using the text from our tag to list all models that have the text from currentTag in them.

# Search models by tag

wl.search_models('My Great Tag')

Remove Tag from Model

Tags are removed from models using the Wallaroo Tag remove_from_model(model_id) command.

In this example, the currentTag will be removed from tagtest_model. A list of all tags will be shown with the list_tags command, followed by searching the models for the tag to verify it has been removed.

### remove tag from model

currentTag.remove_from_model(tagtest_model.id())

{'model_id': 1, 'tag_id': 1}
